v0.7.0

Minor Changes

• 8ff16f9: Palettes, composed components, overlays and the timeline, close-out (feature-004, step 8h):
  0.7.0. The 21 new components —twelve composed, seven overlays on the platform's <dialog>
  and Popover API, the toast and its toaster— the palettes and the optional Knight Lab timeline
  are verified end to end on the composed, palettes and timeline pages of the four example apps and
  documented on the site. Grounds: timeline.css gives TimelineJS's eras a strip of their own below
  the axis labels —with an era, the axis grows to 57px and the era is laid in its lowest 18px, its
  title on a plate of the substrate— so an era's title no longer falls on the major ticks' row and
  its hatching no longer crosses the labels. Angular: a server-rendered SpToaster no longer reaches for
  document when it is torn down —it unlistens F8 only where it listened, on the client— so a server
  render that holds a toaster resolves instead of hanging on a ReferenceError. The seven packages
  move together to 0.7.0; the rendered output of every existing chart is unchanged.

• 62258b7: Fixes found by the end-to-end pass over the composed page (T-223). A disabled SpCollapseItem's
  summary now carries tabindex="-1", so Tab skips it as it skips every disabled control (REQ-522);
  this changes the normalised markup of a disabled item. SpTooltip hides on Escape wherever focus is,
  not only on its trigger, so a tooltip shown by hover can be dismissed without moving the pointer
  (WCAG 1.4.13, REQ-496).

• 449ce95: uiOverlaySync(element, kind, open) on @silverpoint/core/ui (T-215): opens or closes a native
  overlay as its state says —showModal(), show() or close() for a <dialog>, showPopover() or
  hidePopover() for a popover— only when the element is in the other state, so no second close or
  toggle event fires. Without the Popover API a popover stays in the page's flow.

• d4d569d: Palettes, the composed components' and overlays' core, and the timeline's (feature-004,
  T-200..T-208). On the new subpath @silverpoint/core/palettes: resolvePalette, paletteStyle, PALETTE_PROPERTIES,
  contrastRatio, checkPalette, PALETTE_PAIRS and six verified presets (silverpoint,
  sanguine, sepia, ironGall, verdigris, indigo); the Palette type on the main entry.
  A palette value is accepted only if it is a CSS colour (an allowlist). On @silverpoint/core/ui:
  uiSortRows, uiPageWindow, uiPagination, uiNumberValue (now also reporting the range as
  drawn), uiNumberStep, uiInitials, uiListKey, uiTypeahead, uiPlace, uiAnchor; ten new
  glyphs in UI_GLYPHS; and the view trees of SpSurface, SpGlyph, SpTable, SpPagination,
  SpBreadcrumb, SpAvatar, SpAvatarGroup, SpStatistic, SpDescriptions, SpTimelineList,
  SpCollapse, SpCollapseItem, SpEmpty, SpResult, SpTextarea and SpInputNumber, and of
  the overlays SpModal, SpDrawer, SpPopover, SpTooltip, SpSelect, SpDropdownMenu,
  SpToast and SpToaster (native <dialog> and Popover API), with uiTriggerView,
  uiTriggerAria, uiSelectItems, uiMenuItems and uiToastDuration. On the new
  subpath @silverpoint/core/timeline: timelineView, timelineInk, TIMELINE_FRAMES,
  TIMELINE_TONES and the SpTimelineProps / TimelineData types. UI_COMPONENTS gains 21 rows
  with a family field (ui, composed, overlay), three groups and batches A1, A2, B;
  UI_DEMOS gains their 35 states, and @silverpoint/core/ui-demos exports TIMELINE_DEMO. New
  diagnostics SP023, SP024 and SP025.

  A link's href (SpButton, SpBreadcrumb) now keeps only relative URLs and the http, https,
  mailto and tel schemes, and a headingLevel outside 2..6 draws h3; both warn SP017.

  UiTokens gains the optional backdrop and rowTone levels; resolveUiTokens holds them to 1..4
  and gives a ground that declares none 2 and 1 (T-209).
  A table cell's text stands on a .sp-ui-plate, so a toned row keeps its contrast.

  palette on CommonChartProps, CommonUiProps, DashboardProps and ProviderConfig (T-212):
  resolveUi resolves it provider → dashboard cell → prop and every UI root writes it first in its
  style; dashboardView takes the section's declarations and hands the palette to its cells, where
  inCell merges it under the chart's own; svgString writes it on the <svg>. nestProvider on
  @silverpoint/core/palettes: a nested provider's set fields win and the palettes merge field by field.

• 61e98a2: SpTimeline on @silverpoint/react/timeline, @silverpoint/vue/timeline and
  @silverpoint/angular/timeline (T-221): a Knight Lab TimelineJS timeline inside the ground's surface,
  with @knight-lab/timelinejs ^3.9.13 an optional peer. The server renders the surface, its probes
  and an empty mount; the client imports TimelineJS after render, builds it there without the font
  and theme options, and forwards its seven events (change, loaded, navNext, navPrevious,
  zoomIn, zoomOut, backToStart) as each framework's props, emits or outputs. If TimelineJS cannot
  be loaded, the mount shows the fallback (React's prop, Vue's slot, Angular's
  <ng-template spFallback>), SP025 is warned in development, and nothing throws. Import the subpath
  only with the peer installed. The core's @silverpoint/core/timeline gains timelineMount,
  timelineOptions and TIMELINE_EVENTS, which the three adapters share, and UiSlot gains
  fallback.

Patch Changes

• 3625f7e: Documentation for the 0.7.0 additions (T-224). Each adapter's README lists the 38 UI components and
  shows the palettes and the timeline, with TimelineJS as an optional peer; the grounds README names
  ui.css and timeline.css, and the core README its ui, palettes and timeline entries.
  SpTimelineProps.data gains its documentation comment.
• dec07a4: Fixes found by the pixel gate of the new components (T-219): uiAnchor re-places an overlay when
  its trigger or the overlay changes size, as when a web font replaces its fallback; the AvatarGroup's
  overlap and the dividers between CollapseItems also hold through the display: contents wrappers an
  Angular host keeps around each child; a Vue SpDropdownMenu mounted open focuses its active item, as
  React's and Angular's do.
• 194c0b4: timelineMount (@silverpoint/core/timeline, T-222) builds TimelineJS in a <div> of its own inside
  the mount, so TimelineJS's className rewrite leaves the mount's sp-kl-mount class alone, and hands
  it a copy of data (structuredClone): TimelineJS writes each slide's unique_id into its data,
  which threw on a frozen object such as TIMELINE_DEMO and left the timeline loading forever. An
  error thrown while TimelineJS is built is now handled as a failed load: its container is removed,
  SP025 is warned and the fallback is shown.
