docs: sync documentation after perf/a11y/release-candidate work

- PROJECT.md: Current Status updated (perf/a11y/RC walkthrough all
  done, new report docs added to index).
- FRONTEND-ROADMAP.md: RC PERF-01, RC A11Y-01, and Release Candidate
  walkthrough entries added; known-open-items list updated (2 new
  flags from RC walkthrough, primeng removal blocker, large chunks,
  backend-ready sprint explicitly deferred pending a real API contract).
- KNOWN-ISSUES.md: corrected item 6 (payment modal focus-trap
  assumption was wrong, now actually fixed); added items 9-12 (brand
  contrast failures, Contacts content gap, WYSIWYG editor mislabeled,
  primeng removal blocker); added 2 Fixed entries for this cycle's
  P0s (query-param routing, Categories CRUD).
- Graphify graph regenerated (graphify-out/, cache only, not tracked).
- Obsidian: skipped, no running Obsidian instance in this session.
- No architecture change this cycle (perf/a11y/bug fixes only) — no
  new ADR.
- No application code touched.

 **RC-Premium-01 — Storefront premium UX polish**
 Visual/interaction polish on top of the RC-Visual-02 baseline — no redesign, no logic/route changes. Fixed color-only state signaling app-wide (added `aria-pressed`/`aria-current`/`aria-live` + icon/checkmark pairing to selected swatches, active filters/tabs/sort, toggle buttons), normalized remaining hardcoded hex to design tokens, added hover/focus-visible/active/disabled states across interactive controls, capped legal/CMS prose at 70ch, converted FAQ to native `<details>` disclosures. Four commits (Home/Catalog/Search, Product/Compare/Wishlist, Cart/Checkout, Static Pages). Detail: `docs/STORE_FRONT_UX_REVIEW.md`.

+**RC STORE-01 — Storefront cleanup**
 Closed 2 of the 5 gaps RC-Premium-01 deliberately deferred: category/search skeleton markup migrated to shared `app-skeleton`, dead cart `.email-form` markup/CSS removed. The other 3 (payment modal, cart confirm() dialog, untokenized colors) need an architecture/design-system decision, correctly left alone again. Detail: `docs/STORE_REVIEW.md`.
 
+**RC PERF-01 — Performance audit** (production-readiness, app-wide)
+Initial bundle **1.47 MB → 1.12 MB raw (−24%)**: biggest win was lazy-loading en/hy i18n packs (346 KB were eagerly loaded regardless of visitor language), plus a dead `items-carousel`/primeng-only component deleted, dead global CSS removed. RxJS/change-detection audit found the codebase already clean (0 leaks, 190/191 components already OnPush). Detail: `docs/PERFORMANCE_REPORT.md`.

+**RC A11Y-01 — WCAG 2.1 AA audit** (storefront, builder, backoffice)
+Added the app's first skip link (didn't exist anywhere before), fixed cart's custom payment modals having zero focus-trap, fixed `app-icon`'s "decorative by default" claim never actually being implemented, fixed 2 keyboard-inaccessible drag-and-drop reorder UIs (Builder homepage/footer, Backoffice categories), fixed an undefined `--color-primary` token in Builder, fixed admin sidebar nav announcing itself as "Dashboard" everywhere. Contrast fixes applied where safe; genuine brand-color contrast failures flagged for theme-owner sign-off, not changed unilaterally. Detail: `docs/ACCESSIBILITY_REPORT.md`.
+
+**Release Candidate — live browser walkthrough** (storefront, builder, backoffice)
+Found and fixed **2 P0s**: (1) `language.guard.ts`'s legacy-URL redirect broke query params on every route app-wide (silently dead-ended any bookmarked/shared deep link with query params); (2) Backoffice Categories CRUD was completely broken end-to-end — wrong gateway-resolution fallback always picked the real HTTP gateway instead of the local mock in this environment, so every create/publish silently failed with zero user feedback. Plus 6 P1s (cart description, compare table raw enum values, search empty-state messaging, footer link 404, missing placeholder image, builder save-bar reset-state bug, backoffice mislabeled button). Detail: `docs/RELEASE_REPORT.md`.

 ## Sprint status
 
 **Sprint 30 — Final Release**: verify pass re-run 2026-07-23 (tsc --noEmit, `npm run build`, `arch:check:boundaries`, `arch:check:cycles`) — all green, only pre-existing bundle-budget warning. Working tree otherwise clean. Only remaining item: `git push` of 10 local `B2B` commits to `origin/B2B` — awaiting explicit user go-ahead (declined once already this sprint, per safety rules re-ask each time). Full checklist: `docs/SPRINT-PLAN.md`.

 ## Known open items (not yet scheduled)
 
 Full detail in `docs/KNOWN-ISSUES.md`. Summary:
-- Payment modal / bank-payment iframe on Cart still custom (own focus-trap, multi-step state) — candidate for `app-dialog` migration.
+- Payment modal / bank-payment iframe on Cart still custom (own focus-trap, multi-step state — note: RC A11Y-01 added a real focus-trap to it, but it's still not `app-dialog` itself) — candidate for `app-dialog` migration.
 - Cart's native `confirm()` on clear-cart — no existing confirm-dialog pattern to follow yet.
+- Genuine brand-color contrast failures (`--border-color`, `--success/warning/error/info-color` as text) — flagged by RC A11Y-01, need theme-owner sign-off before changing.
 - `stars.component` rating glyph color and a few legacy hex literals in `pages/category`/`pages/search` have no exact token match — needs a deliberate token-extension decision.
 - Homepage hero-to-categories dead-space gap — traces to mock bootstrap config, not a code defect; needs real-tenant-data reproduction.
+- Footer "Contacts" link has no static-page content in mock data — needs a content decision (found during RC walkthrough).
+- Builder's static-page body editor is hidden inside a collapsed "Advanced" section, mislabeled "Source HTML (advanced)" — works, but needs a navigation/labeling decision (found during RC walkthrough).
 - ~178 missing `adminXxx.*` i18n keys across admin backoffice.
 - Theme Mode (dark/system) selector has no runtime CSS effect — real feature project, not a wiring fix.
 - `dynamic-renderer/` pipeline exists but is unwired — needs a finish-or-delete decision.
+- `primeng`/`primeicons` still in `package.json` despite the only consumer being deleted (RC PERF-01) — `npm uninstall` blocked by an unrelated broken `barry-cache` devDependency (`ETARGET`); fix that first.
+- 2 large lazy chunks (`project-editor` 320 kB, `catalog-container` 126 kB) — no mechanical split found, needs a dedicated task.
+- Backend integration: still mostly PLANNED/mock — a "backend ready" sprint was attempted and explicitly deferred (2026-07-24) pending a real API contract (no `docs/BACKEND-API.md`, no live endpoint confirmation beyond what's already CURRENT).
