089ae5bd0a docs(origin): align brand identity with CHARTE_GRAPHIQUE_TALAS (Sprint 2 follow-up #4)
ORIGIN_UI_UX_SYSTEM.md (v2.0.0 lock) defined a generic Tailwind sky-blue palette
(#0ea5e9 etc.) that contradicted the SUMI ink-wash brand identity (#0098B5
Mizu cyan unique + data viz pigments). This commit aligns the ORIGIN lock.

New file : ORIGIN_BRAND_IDENTITY.md (v1.0.0)
- Codifies the canonical SUMI palette (charte §4)
- Documents data viz exception (charte §4.5 — 5 viz pigments allowed)
- Lists all immutable rules (no #FFFFFF, no #000000, cyan unique, etc.)
- Points to source : packages/design-system/tokens/ + CHARTE_GRAPHIQUE_TALAS.md
- Documents motion classification (goutte/trait/lavis/vague/maree)
- Documents typography (Space Grotesk + Inter + JetBrains Mono, woff2 only)
- Documents ESLint guard (no-restricted-syntax for hex literals)

Updated : ORIGIN_UI_UX_SYSTEM.md
- Header note marks Sections 2/3/4 as superseded by ORIGIN_BRAND_IDENTITY.
- The interaction patterns / accessibility rules / anti-patterns / user flows
  remain authoritative. Only the numeric palette/typography stays.

Updated : checksums.txt
- New SHA-256 for ORIGIN_UI_UX_SYSTEM.md (header note added).
- New entry for ORIGIN_BRAND_IDENTITY.md.

Closes Sprint 2 follow-up #4. Sprint 2 fully shipped.
