v0.17.0 — plain HTML & CSS consumption

Added

• dssoca/vanilla.css — every component's styles for plain-HTML pages (DS-0148). A new
  stylesheet generated in prepack (scripts/build-vanilla.mjs) from the components' own
  compiled <style> blocks — never hand-written, so it cannot drift from the Svelte components.
  Each component is wrapped in a donut @scope (.ss-root) to (<every other root>) block so the
  unprefixed internal class names stay isolated in a global sheet (root-led selectors get a
  zero-specificity :where(:scope) prefix so they still match the root); @keyframes are hoisted; the
  four :global() rules are emitted root-anchored. The markup contract is the exact DOM the Svelte
  components render. Load it after theme.css / tokens.css. Requires CSS @scope
  (Chrome/Edge 118+, Safari 17.4+, Firefox 2026+) — no fallback.
• dssoca/vanilla.js — small, dependency-free behaviours for that markup (DS-0148). An ES
  module (relative imports only, loads straight from jsDelivr) that wires, via document-level
  event delegation: Modal (data-ss-modal="#id" openers, data-ss-dismiss, backdrop click,
  data-ss-static / data-ss-no-esc), Accordion (data-ss-multiple), Menu, Tooltip (basic
  placement, no collision engine), Switch, SegmentedControl (data-value), Input clear,
  NumberField steppers and Textarea autosize fallback; bubbling ss:change / ss:select events;
  a framework-free toast / toasts API with the same names and defaults as the Svelte one
  (renders the Toaster DOM; swipe-to-dismiss not ported); iconSvg / hydrateIcons for
  <span data-ss-icon="name"> placeholders; mount(root); and re-exports of
  applyDesignConfig & friends.
• CSS-only Spinner in vanilla.css: steps() keyframes generated from SPINNER_VARIANTS
  drive .frame:empty::before; pick the glyph set with data-variant on the root.
• src/lib/icons.ts and src/lib/spinner-frames.ts now hold BUILTIN_PATHS / registerIcon
  and SPINNER_VARIANTS; Icon.svelte / Spinner.svelte re-export them, and toast-core.ts
  holds the toast types + timer shared by both stores. Public API unchanged.

Changed

• The three unprefixed component @keyframes (pulse, skeleton-pulse, sk-shimmer) are now
  ss-logs-pulse, ss-metric-skeleton-pulse, ss-svc-shimmer so they are safe in a global
  sheet (Svelte hash-scoped them before; no visual change).

Deprecated

• The global .ss-table layout class in theme.css (DS-0148) — it predates the Table
  component, whose root shares the name. Unchanged in 0.17.0, removed in 0.18.0 (DS-0149).
  Use <Table> or its markup + vanilla.css (loaded after theme.css).

Docs

• New guide: Plain HTML & CSS (/vanilla) — install (npm + CDN), load order, the @scope
  browser floor, the data-ss-* contract, the toast API, icons, the CSS-only list, caveats.
• Every component page gains an HTML section whose markup is produced at docs build time by
  server-rendering the real component (+page.server.ts + svelte/server), with the scoping
  hashes stripped and the vanilla hooks added — so snippets can never drift. Each component doc
  declares an htmlExample (props + snippets + behaviour: 'js' | 'css'), enforced by
  pnpm docs:test. README, DESIGN.md and CLAUDE.md replace the 0.3.0 "hand-rolling
  .ss-btn no longer works" policy with the vanilla policy. A live HTML playground is a planned
  follow-up.
