@microcharts/react@0.3.0

Minor Changes

• #23 c5854a0 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

• #23 c5854a0 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.

• #23 c5854a0 Thanks @ganapativs! - Improve npm and search discoverability: expand keywords, add a funding link
  (GitHub Sponsors), and a structured author (name/email/url). Metadata only — no
  API, runtime, or visual changes.
