docs(04): UI-SPEC.md status approved — 5/6 PASS + 1 FLAG non-blocking (dim 4 inherited type scale)

UI-checker verdict: APPROVED. Dimension breakdown:
- 1 Copywriting: PASS (17-key matrix inherited + locked; zero new copy)
- 2 Visuals: PASS (no new screen; dark-logo is stroke binding change)
- 3 Color: PASS (Loom palette inherited; semantic accents declared)
- 4 Typography: FLAG (8 sizes / 4 weights exceed standard thresholds but
  correctly captured as Phase 1-locked inherited from operator brand-fit
  ack 2026-05-20; Phase 4 adds zero new sizes/weights) — non-blocking
- 5 Spacing: PASS (all multiples of 4; locked; no new values)
- 6 Registry Safety: PASS (vanilla DOM + DOMParser; no shadcn; no third-party)

Three checker observations addressed:
1. `?url` → `?raw` bundling: correctly preserves @crxjs auto-WAR (SVG
   content stays in JS bundle as string literal vs base64 data URL)
2. A17.8 sub-check update: concrete enough (raw-SVG-source string-search
   for `currentColor` + `viewBox='0 0 32 32'`); optional A17.8a/A17.8b split
   well-described
3. Dark-mode contrast: deep-indigo stroke on madder-orange wrapper is
   readable; operator empirical checkpoint (acceptance criterion #6) is
   the designated gate for WCAG ratio judgment

Implementation contract = 5 file edits + 6 acceptance criteria. Planner can
now use UI-SPEC as design context for the visual-polish Phase 4 plan.
