Kjell Tore Guttormsen f1fecf39b8 feat(shared): Tier 3 wave 2 (12 components) + self-hosted fonts 
Two changes in one commit because they were prepared together and the
component demos depend on the new self-hosted fonts.css.

Tier 3 wave 2 — 12 new components
---------------------------------
Adds components-tier3-supplement.css (886 lines) and 12 isolated demo
HTML pages under shared/playground-examples/components/:
toxic-flow chain, fleet-overview, kanban Keep/Review/Remove,
maturity-ladder, classify-and-transform, cycle-ribbon,
persistent-antipattern, suppressed-signals, ExpansionCard, ReadMore,
FormProgress, Aspirational-vs-Committed.

Reuses existing tokens — no new CSS custom properties. Honors the
Phase 1 feedback rules: no large pink areas for body text, severity-red
distinct from failure-red, dark mode via existing [data-theme="dark"].

Provenance: components-tier3-supplement.css and the 12 demo bodies were
authored by claude.ai/design (separate Anthropic instance) on 2026-05-03.
This commit only integrates them — path rewrites, font swap, generic
name substitution in fleet-overview demo data, README updates.
base.css from the export was deliberately NOT taken in because it
reverted the inline-message contrast fix from v0.1.

Self-hosted fonts (Inter, JetBrains Mono, Source Serif 4)
---------------------------------------------------------
Replaces all fonts.googleapis.com / fonts.gstatic.com requests with
.woff2 files bundled at shared/playground-design-system/fonts/.

Why:
- No data leaked to Google about end-user IPs and User-Agents.
- GDPR-safe for Norwegian public-sector deployments.
- Works offline / behind air-gapped firewalls.
- Forkers downloading the marketplace get a complete bundle.

All three families are SIL Open Font License 1.1 — license texts
included alongside the woff2 files. Source Serif 4 woff2 generated
locally from the upstream OTF release using
fonttools ttLib.woff2 compress; Inter and JetBrains Mono are
unmodified upstream webfont releases.

Total bundle: 9 woff2 files, ~940 KB. New fonts.css declares all
@font-face rules with font-display: swap. All 6 example HTMLs and 12
new component demos load it via a single relative path.

Verified
--------
- Privacy grep returns empty across plugins/ and shared/
- Google Fonts grep returns empty across shared/*.html
- Smoke test via python -m http.server: HTML + 7 stylesheets +
  Inter-Regular.woff2 all return 200

Doc updates
-----------
- shared/playground-design-system/README.md: file tree updated,
  Quick start snippet shows fonts.css link, "Self-hosted fonts"
  section added
- shared/playground-design-system/fonts/LICENSES.md: combined attribution
- README.md (root): Tier 3 wave 1+2 component list, Privacy-first bullet
- CLAUDE.md (root): tree entry expanded for new components + fonts

Font Licenses

All three font families bundled with Playground Design System are licensed under the SIL Open Font License, Version 1.1 (OFL-1.1). They are free to use, modify, embed, and redistribute under the terms of OFL-1.1.

Provenance

Files in this directory were obtained from the upstream release artifacts linked above on 2026-05-03. Source Serif 4 woff2 files were generated locally from the desktop OTF release using fonttools ttLib.woff2 compress; all others are unmodified from upstream webfont releases.

Why bundled

These fonts ship with the design system to eliminate runtime requests to external CDNs (e.g., fonts.googleapis.com). This guarantees:

  • No data leakage about end-user IPs / User-Agents to third parties.
  • GDPR compliance for Norwegian public-sector deployments.
  • Functioning Playgrounds in offline / air-gapped environments.

Each Playground HTML loads ../shared/playground-design-system/fonts.css, which declares all @font-face rules pointing at the .woff2 files in this directory.
