  @ganapativs! - Robustness, consistency and legibility pass across all 106 charts.
  Most of this is invisible if your charts already looked right; the parts that aren't are listed under "behaviour
  changes" below.

  Fixed: charts that could hang, crash or vanish. These were all reachable from ordinary props, and each now has a
  regression test.

  • TapeGauge never finished rendering when value was large enough (about 1e16 and up) that its tick step fell below
    one ULP — the tick loop stopped advancing and spun until the tab died. Ticks are now counted, not accumulated, and
    capped.
  • TraceFold hung forever on a parent graph containing a cycle (a span parented to itself, or any two-span loop).
    The critical-path walk now tracks what it has visited.
  • Marks silently disappeared whenever a scale's domain span was infinite — including finite data whose arithmetic
    overflows, such as a Waterfall running total past 1e308. An infinite span yields a slope of exactly 0, which
    passed the old finite check and then produced NaN coordinates. scaleLinear now validates the span itself.
  • PictogramRow's total, Progress's segments, Thermometer's ticks and FoldedDayBand's bins allocated
    one node per unit with no ceiling, so a raw count passed by mistake could exhaust memory. All four now saturate.
  • Charts derived bounds with Math.max(...array), which throws RangeError past roughly 125k elements. Every such
    site now uses a stack-safe fold, so a long series renders instead of crashing.
  • CyclePlot threw on period={NaN} (an empty input field yields exactly that), HeartbeatBlip divided by a zero or
    non-finite window and could put "in the last NaN minutes" into its accessible name, and ActivityGrid accepted an
    unvalidated domain and painted fill-opacity="NaN".

  Fixed: accessibility and inline seating.

  • Labels sitting on a solid mark (HeatCell's upper steps, TimeInRange zones, EventTimeline spans) were rendering
    in body ink instead of on-fill ink — dark-on-dark on the strongest cells. The stylesheet always won over the fill
    attribute these charts were setting, so the intended colour never applied.
  • A decorative interactive chart (summary={false} or live={false}) lost its inline baseline seat, which also
    detached its readout chip and hit box from the mark by up to a seat's height. The live region — which carries the
    seat — now stays mounted and is silenced by emptying it.
  • Visible readout chips and idle labels on MicroDonut, GradeProfile, GardenGrid, QuantileDots and
    EventTimeline composed English inline instead of going through the strings contract, so they stayed English in a
    localized app.

  Behaviour changes worth knowing.

  • Interactive charts now claim only the horizontal touch gesture (touch-action: pan-y pinch-zoom) rather than all
    gestures, so a chart no longer traps the page scroll under a finger; a scroll that takes over now clears the
    highlight.
  • HeatCell and HeatStrip build their step colour by mixing the accent into the band rather than ramping opacity,
    so the steps stay distinct on dark surfaces. The fill moved to the stylesheet, which restores the high-contrast
    (forced-colors) mapping that an inline fill was overriding.
  • DotPlot, Dumbbell and Slope scale their label type and row-name budget with the chart's size instead of using
    a fixed 6-unit font and 6-character cap, so figure-scale charts read properly. Slope steps its type down until the
    labels fit rather than dropping them.

  Added.

  • strings on the static Sparkline, SparkBar and MusicStaff. Their generated accessible name was English-only
    with no override short of writing the whole summary yourself.
  • labelAt on StackedArea, so endpoint share labels can track a scrubbed column.

  Breaking (pre-1.0), types only. SummaryStrings gained quantileDotsChip, quantileDotsOdds and
  timelineFallback. If you supply your own strings object for QuantileDots or EventTimeline, add those three
  templates; every other consumer is unaffected.

  @ganapativs! - Breaking (pre-1.0 API freeze): prop-name consistency pass. Same
  prop name must mean the same thing across the catalog. Collisions found in the pre-1.0 audit are renamed; behaviour is
  unchanged — pass the new name, get identical output.

  Chart	Old	New	Why
  MusicStaff	range	mode	range is the peer-band recipe on BenchmarkStrip
  PercentileTrace	bands	showBands	bands is qualitative thresholds on Bullet
  FoldedDayBand	bands	percentiles	⇑; avoided levels (already DepthWedge / GradedBand)
  Waterfall	start	open	start collided with PolarClock / ActivityGrid; avoided from (Delta)
  PolarClock	start	origin	⇑
  ActivityGrid	start	anchor	⇑
  OrbitStatus	alert	threshold	Decision cutoffs spell threshold elsewhere
  CyclePlot	trend: "line" | "none"	trend?: boolean	Matches MicroScatter

  Also in this release: chart polish (label defaults, annotation hosts, motion safety); interactive scrub/HOP
  re-render wins (picker SVG cache, Sparkline memo overlays, EnsembleGhosts DOM hop); size sync tolerates over-budget
  size-limit --json; marketing band ~2–7 kB interactive · ~1–4 kB static.

  Non-breaking: MicroDatum.formatted + readout on interactive pickers (hide in-chart chip, render the chart's
  own display string elsewhere); empty-state seat on 11 charts; LiveRegion on dice-pips / tally-marks / hourglass;
  data-mc-ink on Slope + forced-colors for data-mc-status; Delta / Bullet / ActivityGrid / TokenConfidence English
  via strings-*; core clamp / lastFinite reuse; docs registry + MDX synced (catalog.json / llms surfaces
  regenerate); gallery collections + comparison/SEO doc pages; CI splits core/dom/browser projects.

  Examples microsites migrate after publish — not in this release.

Minor Changes

• #42
  86dcf8e Thanks
  @ganapativs! - Breaking (pre-1.0 API freeze): remove props that were declared but
  never read. Each of these was accepted by the type signature and documented, but had no effect on rendering,
  geometry, or the accessible summary — passing one did nothing. They are gone rather than fixed where the chart had no
  number and no announcement to apply them to.

  Removed outright:

  • DualSparkline — compareLabel. Never reached the summary or any announcement; the compare series is described
    positionally.
  • DualWindowMeter — damping. Documented as "ballistics for the live entry", but the interactive entry never read
    it; its motion comes from the shared entrance engine.

  Narrowed to the interactive entry only (still available on …/interactive, removed from the static default export,
  where they did nothing):

  • PercentileTrace — unit. Names the reading in the hover/focus announcement; the static entry announces
    percentiles, not individual readings.
  • CalendarStrip, EventRaster, MicroScatter, TokenConfidence — locale (and format on the latter three).
    These statics render lane names, marks and text, never a formatted number; only the readout does.

  Wired up instead of removed:

  • ConfusionGrid — format / locale now reach the accuracy gutter label, which previously hard-coded
    Math.round(v * 100) + "%". Percent formatting goes through the shared cached makeFormatter, so the one number
    this chart renders is locale-aware and honors a custom format. Default output is unchanged. The right-hand gutter
    is measured from the produced string, so a locale that widens the label still fits inside the viewBox.

• #42
  86dcf8e Thanks
  @ganapativs! - One interaction contract across the catalog. 103 of 106 charts now
  share a single picker kernel, so a consumer's handler reads the same on a Sparkline, an ActivityGrid or a MicroDonut.

  This is a pre-1.0 minor with breaking changes — permitted under semver for a 0.x package, but read the Breaking
  section below before upgrading.

  Picker charts (84 multi-unit entries) gain four props on their …/interactive entry:

  • onActive(datum | null) — the hovered / keyboard-focused unit changed
  • onSelect(datum | null) — a unit was activated by click, tap, Enter or Space
  • selectedIndex / defaultSelectedIndex — controlled and uncontrolled selection

  The payload is one shape everywhere: MicroDatum = { index, value, label? }. index identifies the navigable unit
  (documented per chart — a data index where the chart is 1:1 with data, otherwise a unit position). value is that
  unit's primary encoded number, which may be derived — a segment's share, a run's duration, a signed gap, a bin's
  count — and is null where the unit encodes nothing.

  Behavior, everywhere: pointer scrub sets the active unit; click or tap selects and pins it (surviving blur);
  Enter/Space select; Escape clears; re-selecting the same unit clears it; arrows rove on both axes;
  Home/End jump to the ends. On touch, a tap pins and a drag scrubs. Still one listener on the wrapper and pure math
  — never a listener per data point.

  Scalar charts (19 single-unit entries) take the lean half: onSelect only, with { index: 0, value, label? }.
  There is nothing to rove between and no pinned state, so they don't pretend otherwise.

  Deliberately excluded, and documented as such: MinimapStrip is a viewport-window slider and keeps its
  onWindowChange([lo, hi]) range payload; TokenConfidence moves real focus to per-token spans so a screen reader
  reads the text in flow; WindBarb ships no interactive entry at all.

  Breaking

  • Removed onPointFocus (Sparkline, SparkBar, and Waveform's two-argument (index, fraction) form) and
    onRunFocus (StreakSpark). Use onActive, which reports { index, value, label? }. Waveform's fraction has
    no equivalent — the datum reports the bucket index and its peak.
  • PictogramRow's interactive strings prop now takes PictogramStrings, which adds a pictogramUnit template
    so roving announces each unit (it previously announced nothing — an accessibility gap). A custom ScalarStrings
    object needs that one template added. The static entry is unchanged.
  • Charts whose interactive entry hand-rolled geometry that disagreed with their static now mirror the static exactly.
    This corrects rendered output where the two had drifted — most visibly EventRaster (its interactive entry rendered
    43% shorter than its static) and Hypnogram (default size and row-label gutter). Overlays, focus rings and
    hit-tests now land on the marks.
  • Six charts that silently ignored ArrowUp/ArrowDown now accept them as prev/next, matching the rest of the
    catalog.

  Fixed

  • Nine interactive entries dropped consumer children, silently discarding annotations (<Threshold>, <Marker>,
    …).
  • TreeRings' pinned mark had its stroke width overridden by the stylesheet.
  • SproutRow ignored summary={false}; CometTrail mis-indexed its readout when the series contained non-finite
    values; ControlStrip had an index/value misalignment on gappy data; BalanceBeam ignored
    width/height/shape.
  • Honeycomb announced bare numerals to screen readers; it now uses a proper honeycombCell template.
  • CyclePlot's within-slot drill-down (↑/↓ over the observations in the focused slot) is restored.

• #42
  86dcf8e Thanks
  @ganapativs! - Interactive charts now forward className and style to their
  wrapper and size the inner SVG from one shared FILL constant, so the SVG always fills the interactive <span> —
  hover math, crosshairs, and focus rings stay locked to the cursor instead of drifting when the chart is scaled by a
  consumer. Passing style merges (it no longer clobbers the wrapper's display/position/line-height), and
  className composes with the chart's own class. No change at rest — static output is byte-identical.

  Formatters are also hardened against IEEE float noise: makeFormatter snaps its input to 12 significant digits before
  handing it to Intl or a custom format function, so internally-derived values (value - target →
  -3.5999999999999943) render clean without touching real precision.

• #42
  86dcf8e Thanks
  @ganapativs! - Prop-name grammar freeze. Non-negotiable
  #4 says the same prop name means the same thing on every chart —
  an API audit before 1.0 found several names carrying two meanings across the catalog. Each is now spelled one way.

  This is a pre-1.0 minor with breaking renames — permitted under semver for a 0.x package. Every rename below is
  mechanical: pass the new name, get identical output. No rendering, geometry, or accessibility behaviour changed.

  Chart	Old	New	Why
  ABStrips	labels	seriesLabels	labels is a boolean show/hide toggle on 11 other charts
  ShiftHistogram	labels	seriesLabels	⇑
  SpreadBand	labels	seriesLabels	⇑
  Waterfall	total	totalBar	total is a number denominator on 5 other charts
  ChangePoint	max	maxItems	max is a scale denominator on Progress (mirrors <progress>)
  DataDiff	max	maxItems	⇑
  ParetoStrip	max	maxItems	⇑
  CalibrationStrip	variant	mode	13 charts already spelled this mode

  Ohlc	variant	mode	⇑
  StackedArea	variant	mode	⇑
  Waveform	variant	mode	⇑

  427c25a Thanks
  @ganapativs! - defineTheme() gains a strokeWidth token — pin the base data
  stroke weight (--mc-stroke-width) alongside the other geometry/type tokens. A number is stringified as-is (not
  twinned into the dark variant). Additive and identity at its default.

Patch Changes

  427c25a Thanks
  @ganapativs! - Floor charts now seat their baseline flush with the box bottom so they
  align on the text baseline when rendered inline: SparkBar (bar mode), StackedArea, DepthWedge, and GradeProfile. These
  marks are flat fill edges (crispEdges rects / stroke-free, dot-free areas), so filling to the box bottom bleeds
  nothing; the top pad is untouched. SparkBar win-loss keeps its symmetric mid-line inset. No API change.

@microcharts/react@0.4.0

Minor Changes

• #38 0796194 Thanks @ganapativs! - Pre-launch quality pass — expanded annotation hosting, correctness fixes, and internal
  consolidation. All changes are backward-compatible at their defaults; existing charts render
  identically.

  Annotations on 17 value-series charts (was 2). Threshold, TargetZone, Marker, and
  Callout (from @microcharts/react/annotations) can now be passed as children to Sparkline,
  SparkBar, MiniBar, CyclePlot, CitySkyline, ChangePoint, DualSparkline, SpreadBand, ForecastCone,
  ControlStrip, QueueDepth, BurnChart, Waterfall, PercentileTrace, RetentionCurve, WinProbWorm, and
  ErrorBudget. Every host resolves annotation coordinates through the same shared path, so label
  sizing and containment are identical across charts.

  Correctness fixes:

  • weekGrid no longer crashes on a NaN week count or hangs on Infinity — non-finite inputs
    clamp to a single row.
  • divergingStack no longer emits NaN segments when neutralIndex is out of range — an
    out-of-range index is treated as "no neutral".
  • stepOpacity no longer divides by zero at steps === 1 (was Infinity).
  • The interactive MinimapStrip slider always has an accessible name, even when summary={false}
    and no title is given (falls back to the localized viewport sentence).
  • Consumer-supplied annotation labels are now truncated to fit the chart's box, closing the one
    text path that could paint outside the viewBox.
  • The trend-percentage in generated summaries now routes through the locale formatter, so
    non-ASCII-digit locales no longer mix numeral systems in one sentence.

  Summary strings (i18n):

  • TokenConfidence's empty-state string moved from the shared noData key to its own noTokens
    key on SummaryStrings, so it is no longer silently overridden by other charts' noData. If
    you supply custom strings to TokenConfidence, rename noData → noTokens. Rendered output is
    unchanged ("No tokens.").
  • compass8 is now canonically lowercase across WindBarb and StationGlyph (WindBarb capitalizes
    its sentence-initial octant in its own template), fixing lowercase sentence starts when both
    charts' strings were merged. Standalone output is unchanged.
  • heartbeatWindow now reports clean multiples of an hour as hours ("2 hours") instead of minutes
    ("120 minutes").

  Internally, duplicated label-sizing, live-region, gutter, and summary-resolution logic was
  consolidated into shared helpers, and several unused internal exports were removed. No public
  export, prop, or chart was added or removed.

• #38 0796194 Thanks @ganapativs! - Deepen the theming surface — all additive, backward-compatible, and identity at
  their defaults (no visual change to existing charts):

  • defineTheme() — a new opt-in @microcharts/react/theme subpath (zero
    runtime deps, ~2 kB gzip, tree-shaken when unused). Give it one brand accent
    and it derives a harmonized, colour-blind-safe categorical palette and
    hand-tuned-style dark twins in-house in OKLCH — never moving the
    positive/negative hues off their CVD-safe split. Extend a preset, pin any
    token, pass an explicit palette, or extend() a variant; returns
    vars / style / css(selector) (with a prefers-color-scheme: dark block).
  • New tokens — --mc-font-numeric (a dedicated face for figures, tracks
    --mc-font by default), --mc-label-weight, and --mc-density (one scalar
    that scales stroke weight, label size, and small-multiple gap together for
    compact vs comfortable layouts; the plot box is untouched).
  • colors prop — per-instance series colours on the categorical charts
    (SegmentedBar, StackedArea, PartitionStrip, Hypnogram, MicroDonut),
    overriding --mc-cat-* just there.
  • print and eink presets — output-context token bundles for paper and
    grayscale e-paper, answering data-mc-theme / data-mc-preset like the rest.

  The MicrochartCommonProps shared-grammar type is now enforced as a single
  source of truth: a guard test holds every chart's shared props to its canonical
  types.

Patch Changes

• #38 0796194 Thanks @ganapativs! - Ship a minified styles.css. @microcharts/react/styles.css (and the
  per-chart styles/*.css escape-hatch files) now resolve to minified copies in
  dist/ — the shared stylesheet drops from ~8.7 kB to ~2.8 kB gzip. The
  minifier only strips comments and whitespace (no rule merging), so @layer
  membership and cascade order are unchanged. The repo-root styles.css stays the
  unminified source of truth; no API or visual changes.

• #38 0796194 Thanks @ganapativs! - Improve npm and search discoverability: expand keywords, add a funding link

Patch Changes

• 3955472: Fix subpath resolution on StackBlitz and some CDNs. Every export now includes a

  @microcharts/react/sparkline/interactive resolve on loose resolvers that don't
  request the import condition (they previously failed with "file does not
  exist"). Also ship a minified dist — smaller install, and correct bytes for
  consumers that import the ESM directly (Deno, CDNs). No API changes.

@microcharts/react@0.2.0

Minor Changes

• ef2df66: Ship the full catalog: 106 stable chart types (34 core, 26 decision, 23 expressive, 23
  frontier), each with a static React Server Component entry and an /interactive twin, an
  auto-generated accessible summary, opt-in mount animation via @microcharts/react/motion, and
  a CI-gated size budget. Zero runtime dependencies; one shared styles.css. First public release
  usable end to end.

@microcharts/react@0.1.0

Minor Changes

• 69eb408: Batch 1 wave 1 — four scalar glyph charts, each with a static RSC-safe entry and an
  interactive /interactive entry:

  • TrendArrow (./trend-arrow) — direction glyph (arrow/triangle/chevron), flatBand
    noise floor, showValue gutter, positive polarity.
  • StatusDot (./status-dot) — five paired shape+color states (ok/warn/error/off/busy),
    pulse halo, extensible states vocabulary.
  • HeatCell (./heat-cell) — one calibrated color step (shared 5-step ramp), shared
    shape cell vocabulary, optional centered value label.
  • Progress (./progress) — zero-anchored bar + direct percent label, segments
    stepped mode, honest >100% clamp (label carries the truth), burn-down wording.

  Also: EN locale dictionary is now composed from per-shape modules (EN_SERIES +
  EN_SCALAR) so each chart bundles only its own summary templates; new ScalarStrings
  keys scalarDir, flatChange, status, level, progress, remaining, stepsDone.

• 16a3914: Batch 1 wave 2 — five tick/cell strip charts, each with static + /interactive entries:

  • RugStrip (./rug-strip) — raw observations as ticks, density via opacity tiers,
    highlight for "you are here", never downsamples.
  • MiniBar (./mini-bar) — zero-anchored categorical bars, honest data order, sort,
    highlight, signed data with positive polarity.
  • PictogramRow (./pictogram-row) — countable units (●●●○○), true fractional units as
    circular segments (no clipPath ids), renderPoint escape hatch.
  • Seismogram (./seismogram) — event density/intensity ticks, barcode mode,
    spike-preserving max-per-bucket downsampling, summaries always from raw values.
  • HeatStrip (./heat-strip) — 1×N calibrated intensity cells sharing ActivityGrid's
    vocabulary; empty ≠ zero; density-adaptive gaps.

  Kernel fix: scaleLinear now treats denormal-span domains as degenerate (the slope
  overflowed to ±Infinity and 0 × Infinity poisoned coordinates with NaN). New summary
  template modules: EN_CATEGORY, EN_DIST, EN_SLOTS (slot-empty announcements — also
  fixes the latent "No data.." double period in ActivityGrid's null-cell announcement).

• 7bb9ee1: Batch 1 wave 3 — five categorical/relationship charts, each with static + /interactive
  entries:

  • DotPlot (./dot-plot) — named values on one scale; stem flips to a zero-anchored
    magnitude read; deterministic label drop-out and coincident-dot de-overlap.
  • Dumbbell (./dumbbell) — hollow→filled before/after per row; positive valence for
    changes (documented: drop it for ranges).
  • PairedBars (./paired-bars) — actual vs reference on ONE zero-anchored domain;
    grouped or overlay-ghost modes; ref muted by opacity AND width.
  • Slope (./slope) — two aligned columns, one y-domain; neutral until positive;
    greedy endpoint-label dedup; dashed "incomplete" stubs for missing ends.
  • MicroScatter (./micro-scatter) — 2-D position + Pearson r in the summary (claim and
    evidence travel together); linear-only least-squares trend; focal point.

  New summary template modules: EN_PAIRED (fromTo/pairs/slopes…), EN_SCATTER
  (count + relationship tiers). Pluralization fixes in categories/pairs templates.

• 0c92adc: Batch 1 wave 4 — the annotations layer + seven part-to-whole/staged charts:

  • @microcharts/react/annotations — <Threshold>, <TargetZone>, <Marker celebrate?>,
    <Callout> as declarative children; hosts pay only a tiny walker (mark renderers ship
    with this entry). Sparkline/SparkBar retrofitted as hosts.
  • SegmentedBar (./segmented-bar) — composition with a labeled Other rollup +
    largest-remainder percents.
  • HistogramStrip (./histogram-strip) — ≤ 12 uniform bins from raw observations;
    value highlight.
  • MicroBox (./micro-box) — five-number box; min-max or tukey whiskers; refuses fake
    boxes (< 5 raw values → dots; non-monotonic stats → refused).
  • ProgressRing (./progress-ring) — fixed 12-o'clock arc, butt caps, sweep
    countdown mode; threshold-crossing announcements.
  • MicroDonut (./micro-donut) — ≤ 4 wedges + Other; decorative ornament mode.
  • Funnel (./funnel) — stepped columns + retained-share slats; rate-of-first mode;
    inversion notes.
  • LikertStrip (./likert-strip) — diverging valence bar; split/omit neutral (never
    silently dropped); ends/net labels.

  New EN_COMPOSITION string module + distribution templates (binAt, distribution,
  fiveNum, boxStat). Sparkline budget 3.65/4.65 kB pending sign-off (annotations walker).

• 15b0a12: Batch 1 wave 5 — six composed-series charts:

  • Waterfall (./waterfall) — signed deltas bridging into a total; zero-anchored total
    bar on by default; positive="down" for cost bridges.
  • BumpStrip (./bump-strip) — rank trajectory on an inverted ordinal scale (#1 on
    top); change dots; "#5" → "#1" end labels; null = unranked gap.
  • DualSparkline (./dual-sparkline) — series vs benchmark on ONE shared domain;
    dashed/thinner/neutral reference; coincident-endpoint dedup. curve="step" renders
    as linear (documented — keeps the entry inside the 3 kB hard cap).
  • StackedArea (./stacked-area) — share-normalized stack, ≤ 3 series;
    variant="ridge" skin; order="asc".
  • Ohlc (./ohlc) — candle/bars price action, ≤ 20 periods rendered (never averaged);
    valence + geometry encode direction.
  • Horizon (./horizon) — 2–3 fold horizon band; mirror/offset modes; authored
    baseline; summaries read the unfolded values.

  EN_COMPOSED split into per-chart string modules (EN_FLOW/EN_VS/EN_STACK/
  EN_OHLC) so no chart pays for another family's templates. Horizon domain prop is
  now actually wired to the geometry (was silently ignored).

• cf601c5: Batch 1 wave 6 — the two date-structured charts, completing the core-29:

  • CalendarStrip (./calendar-strip) — the last few weeks day by day on a real
    weeks × 7 UTC calendar grid; value days step the shared intensity ramp, zero days
    show the track, no-record days render as outlines (empty ≠ zero), future days are
    blank. 2-D keyboard nav announces real calendar days.
  • EventTimeline (./event-timeline) — spans + point-event diamonds on one linear
    time axis; window clipping is flat-cut honest; coverage merges intervals (overlaps
    never double-count); authored now tick.

  New core: cached makeDateFormatter (UTC-forced for calendar charts) + EN_CALENDAR/
  EN_TIMELINE string modules. core/calendar split into calendar (day parsing) and
  calendar-grid (week-grid/year math) so ActivityGrid stops carrying grid math it never
  calls. Fixed: normalizeShares could emit a negative share when the float remainder
  landed on a denormal-tiny entry (property-test counterexample) — remainder now folds
  into the largest share.

• 425f933: Batch 2 wave 1 — five decision micrographs, each with a static RSC-safe entry and an
  interactive /interactive entry:

  • CoverageStrip (./coverage-strip) — presence/absence on a time strip; null (no
    measurement) is hollow, 0 (a measured zero) is filled, so absence never masquerades
    as zero. expected makes trailing missingness count; mode="intensity" shades measured
    cells; label="percent".
  • BenchmarkStrip (./benchmark-strip) — a focal dot against the peers' empirical
    quantile bands; the stated percentile uses a mid-rank rule; small samples fall back to
    min–max. range, median, label, positive.
  • PercentileLadder (./percentile-ladder) — p50/p90/p99 as graduated ticks on a
    zero-anchored track; scale="log" renders an in-chart log tag (never silent);
    ps, label, dots.
  • GradedBand (./graded-band) — nested central intervals graded by opacity, never a bar
    from zero; levels (1–3), value dot, softEdge, label="median".
  • IconArray (./icon-array) — one rate made countable in a fixed N-unit grid with the
    denominator visible; no partial-unit fills (sub-unit rates are flagged); of (10/20/100),
    label, shape, positive.

  Also: new per-family summary-string modules EN_COVERAGE, EN_QUANTILE, EN_FREQ (each
  chart bundles only its own templates) and the corresponding SummaryStrings keys.

• 425f933: Batch 2 wave 2 — BurnChart (./burn-chart), static + /interactive entries:

  • BurnChart — a dashed plan line (full length to the deadline), the solid
    actual line to today, a today tick, and a dotted projection whose slope
    is a linear fit over the last max(2, ⌈today/3⌉) actual points — provisional by
    construction, never a smoothed or optimistic curve. label="gap" states the
    signed schedule landing vs the deadline (e.g. +2 d), colored by valence with
    the sign in text. mode="down" | "up", projection={false} for retrospectives.
    A flattened recent burn never reaches zero: no landing, and the summary says
    "not finishing at the current pace" outright.

  New EN_BURN summary module (burn, burnNoPlan, burnLanding, burnFlatlined,
  burnAt, burnAtProjected, burnRemain/burnDone).

• 425f933: Batch 2 wave 2 — ControlStrip (./control-strip), static + /interactive entries:

  • ControlStrip — a Shewhart individuals control chart: the band is center ± 3σ̂
    where σ̂ = mean moving range ÷ 1.128 (the individuals estimator, stated —
    sample SD is not used, it inflates limits under drift). In-control points are bare
    vertices; only out-of-control points are marked (ringed, negative). limits="sigma" | "percentile" (empirical p0.135/p99.865 for skew), baseline for a golden-period
    center, rules="we" for the enumerated Western Electric subset (WE-1/2/4, no rule
    fires silently), dots="all" for sparse series. Fewer than 10 points → dashed band
