docs: consolidate documentation and archive temporary reports

Step 1-2 (audit + plan): classified 35 project markdown files into
Core/Architecture/ADR/Temporary-audit/Sprint-report/Generated-review/
Duplicate/Obsolete/Historical. Agent-tooling files (.agents/skills/**,
.superpowers/**, docs/context/**, CLAUDE.md/GEMINI.md/AGENTS.md/
.github/copilot-instructions.md) explicitly out of scope — intentional
per-tool duplication, not documentation debt.

Step 3 (merge, no information lost):
- docs/PROJECT.md -> docs/PROJECT_INDEX.md, rewritten as the single
  entry point: system overview, living-doc index, archive pointer,
  current status, and a critical-finding callout up top.
- docs/backend/BACKEND-INTEGRATION.md -> docs/BACKEND_API.md,
  docs/backend/REMAINING-BACKEND-WORK.md ->
  docs/BACKEND_API_REMAINING_WORK.md (also folded in a legitimate
  uncommitted status update that had been sitting unstaged all
  session: categories marked DONE, order-creation endpoint noted done).
- RELEASE-NOTES.md merged into CHANGELOG.md (was a near-duplicate of
  the same release content in friendlier prose), then deleted.
- KNOWN-ISSUES.md: added item 13 (see below) and item 14 (missing
  canDeactivate on admin/products edit, from the archived PROJECT-STATE
  audit, re-verified still true); added a correction note to Fixed
  item 7.
- All cross-references to renamed/moved files fixed across every
  kept doc (grep+sed pass, then verified with a link-existence check
  across all 58 in-scope markdown files -> 0 broken links).

Step 4 (archive, nothing deleted without merging first): created
docs/archive/, moved 19 files there (3 root sprint reports, 1 platform
report, SPRINT-PLAN.md, and 14 one-off audit/review/report docs).
Added correction headers to the 3 archived docs whose conclusions were
affected by the finding below, rather than silently leaving them
misleading.

Step 5: docs/PROJECT_INDEX.md rewritten per the mission brief -
someone opening the repo should understand the whole system from it.

IMPORTANT FINDING (surfaced during this audit, not the mission's
primary goal but too significant to bury): pages/category/*,
pages/search/*, pages/item-detail/*, pages/info/**, pages/legal/**
(40+ files) are entirely unrouted dead code - app.routes.ts's
cmsContentRoutes is a literal empty array, and category/search/product
routes redirect to CatalogContainerComponent/
ProductDetailsContainerComponent, not these files. Confirmed against
app.routes.ts directly and cross-checked against FRONTEND.md's own
routing description. This means several fixes from earlier this cycle
(RC-Premium-01, RC STORE-01) and the dead-code cleanup sprint's
conclusion that these files were live were all wrong - documented as
KNOWN-ISSUES.md item 13, flagged at the top of PROJECT_INDEX.md, and
noted on the 3 archived docs whose conclusions it affects. No
application code was changed to fix this (out of scope per this
session's 'documentation only' constraint) - it needs a wire-it-up-or-
delete-it decision first.

Verification: tsc --noEmit clean, npm run build green, all markdown
links across 58 in-scope files resolve (checked programmatically).
No application/Angular/backend code modified.

+# Platform Standardization Report
+
+Date: 2026-07-09
+Scope: Sprint 11.5 - Platform Standardization
+
+## Objective
+
+Standardize the frontend platform before Admin Platform work without adding new marketplace features.
+
+## Summary
+
+The sprint delivered a platform-wide standardization pass across architecture boundaries, legacy cleanup, widget metadata support, translation coverage, theme token normalization, and architecture documentation updates.

+
+## Technical Debt Removed
+
+- Removed duplicate catalog search-history service implementation and consolidated on core search history service.
+- Removed legacy variant naming from active application-layer styles/templates (`novo` / `dexar` remnants in `src/app/**`).
+- Eliminated hardcoded UI strings identified in audited runtime pages/components by introducing translation keys.
+- Standardized global token surface for spacing and transition variables.
+- Added explicit widget metadata support surface for animation/style/permissions and normalized metadata propagation through dynamic rendering.
+
+## Architecture Audit Result
+
+Target flow: UI -> Facade -> Domain -> Infrastructure -> Backend
+
+Result:
+
+- Audited website feature containers/components for direct forbidden dependencies.
+- No active component-level `HttpClient` usage found.
+- No active component-level DTO imports found.
+- No active component-level `environment` access found.
+- Facade/container orchestrations remain in place for catalog and product UX flows.
+
+## Legacy Cleanup Result
+
+Searched and addressed:
+
+- `isMarketplaceVariant`
+- `marketplaceVariant`
+- `projectName`
+- legacy variant naming usage in app layer (`novo`, `lavero`, `dexar`)
+
+Result:
+
+- No remaining `isMarketplaceVariant`, `marketplaceVariant`, or `projectName` matches in `src/**`.
+- No remaining `novo`/`lavero` matches in `src/app/**`.
+
+## Bootstrap Audit Result
+
+Config representability status:
+
+- Core page/section/widget configuration remains bootstrap-driven.
+- Widget metadata support expanded in contracts and dynamic renderer.
+
+Documented gaps (no backend changes implemented):
+
+- Full role/permission enforcement for widgets is limited by current auth session shape (no roles/permissions in session model).
+- Catalog popular-search defaults are still facade-local constants and should be modeled in bootstrap catalog config.
+- Optional persistent-storage key prefix override is not yet modeled in bootstrap schema.
+
+## Widget Audit Result
+
+Support status:
+
+- `title`: supported
+- `subtitle`: supported
+- `visibility`: supported
+- `layout`: supported
+- `animation`: supported
+- `style`: supported
+- `permissions`: supported (auth-gate baseline)
+
+## Translation Audit Result
+
+- Remaining hardcoded UI strings found in audited pages/components were replaced with translation keys.
+- Translation schema and locale resources were updated for new keys.
+
+## Theme Audit Result
+
+Standardized token set ensured:
+
+- Spacing: `--space-xs`, `--space-sm`, `--space-md`, `--space-lg`, `--space-xl`
+- Radius: `--radius-sm`, `--radius-md`, `--radius-lg`
+- Shadows: `--shadow-sm`, `--shadow-md`, `--shadow-lg`
+- Transitions: `--transition-fast`, `--transition-normal`, `--transition-slow`
+
+Runtime mapping now propagates spacing/transition tokens through theme engine.
+
+## Validation
+
+Executed:
+
+- `npm run build`
+- `node tools/architecture/check-boundaries.mjs`
+
+Expected acceptance target:
+
+- Build with no warnings
+- No legacy marketplace conditions in app layer
+- No environment-driven business logic in feature/business layers
+- No duplicate implementations in catalog search history path
+
+## Remaining Recommendations
+
+1. Extend auth session model/contracts to include role and permission claims, then enforce widget role/permission checks in dynamic layout.
+2. Move `SearchFacade.popularSearches` to bootstrap `catalog` settings to remove remaining hardcoded discovery defaults.
+3. Add bootstrap-configurable storage namespace/prefix for all local persistence services.
+4. Continue translation audit on legacy pages outside audited standardization scope (especially static/legal and long-tail utility pages).
+5. Consider normalizing project naming in build metadata (`angular.json` project id/output naming) in a dedicated infra-only cleanup sprint.
