  i18n, BADGE_REC_COLOR madder #b2543d, chrome.i18n fallback,
  harness A18-A22, operator brand-fit ack 2026-05-20 'all good')
- Phase 1 plan count: 13 → 14 plans (01-01 through 01-14)
- Progress table Phase 1 row: 7/7 Complete → 13/14 Executing with
  closure-status disambiguation (functional via Plan 01-13;
  design/brand via Plan 01-12; Plan 01-10 welcome tab remains)

REQUIREMENTS.md changes:
- REQ-install-clean: [ ] Pending → [x] Complete (2026-05-20)

  baseline UNCHANGED
- Traceability table: both requirements moved from Phase 3/4 Pending
  to "Phase 1 closure via Plan 01-12" Complete
- Footer: last-updated 2026-05-15 → 2026-05-20 with annotation
  noting the requirements flipped at Plan 01-12 closure

No code changes; pure documentation closure sync.
