✨ style(web): unify design system across default frontend
🔤 Typography
- Fix --font-sans stack: 'Public Sans Variable' was never applied (wrong family name), add CJK fallbacks (PingFang SC / Microsoft YaHei UI / Noto Sans SC)
- Sync <html lang> with i18n language for correct CJK glyph selection
- Remove dead fake font system (font-provider.tsx, config/fonts.ts, --font-inter/--font-manrope)
- Typography contract: 3-tier headings, arbitrary text-[10px]/[11px] → text-xs (46 files), no uppercase table headers, font-bold → font-semibold
- Numbers use tabular-nums only; font-mono reserved for keys/IDs/code (29 files)
🎨 Color discipline
- Retire StatusBadge string-hash rainbow (autoColor → neutral); all variants resolve to 5 semantic voices
- Add tintedBadgeClassMap as the single tinted-pill recipe
- Replace hardcoded emerald/amber/rose/sky classes with semantic tokens across ~30 files (timing badges, progress bars, system panels, pricing, rankings, log row tints)
- Drop all !important text overrides and [font-family:var(--font-body)] hacks
🧘 Motion restraint
- Remove admin entrance animations: table row stagger, card hover lift/shadow, button press scale, dashboard shimmer line
- Neuter page-transition stagger components into plain wrappers; page transitions reduced to pure opacity fade
- Decorative motion stays landing-only
📐 Shape
- Single radius source: --radius 1rem → 0.625rem
- Sparklines use solid chart tokens instead of decorative gradients
- PanelWrapper: border-only (no shadow), align radius with Card
📏 Guardrails
- Add "Design System Discipline" section (3.10.1) to web/default/AGENTS.md
✅ Verified: tsgo typecheck clean, rsbuild production build passes
