moh dc21c33867 ADDED - Admin SEO page, robots/sitemap hardening and media/maintenance security fixes
SEO
- New Settings > SEO admin page (seo_settings in app_config): indexing switch,
  Google/Bing verification, X handle, JSON-LD identity (Person/Organization,
  sameAs), per-locale keywords, readiness checklist and open links for
  sitemap.xml / robots.txt / manifest.
- robots.txt is now dynamic: disallows admin, api, success and coming-soon
  paths; blocks everything while indexing is off or maintenance is on.
- sitemap.xml carries hreflang alternates per URL, lists only categories with
  published projects, and is empty while hidden.
- Metadata: robots + verification meta, og:locale in de_DE/en_US/ar_AR form,
  alternateLocale, twitter site/creator, project cover as OG image with
  article type, noindex on /success and /coming-soon.
- JSON-LD: WebSite + publisher graph on all public pages, CreativeWork per
  project (view-mode independent).

Security
- Maintenance bypass now requires a correctly signed admin cookie; the
  middleware previously only checked the cookie existed. Token helpers moved
  to lib/admin-session-token.ts (shared by proxy.ts and lib/admin-auth.ts).
- Media uploads: magic-byte validation against the declared type, SVG
  sanitization (script/handlers/foreignObject/javascript: rejected), upload
  folder sanitized, kind inferred from the real file.
- Media route: fixed prefix-based path check that accepted sibling
  directories, unknown extensions return 404, nosniff header, CSP sandbox on
  SVG, gif content type added.
- External media URLs: protocol-relative (//host) URLs rejected.

Portfolio
- Project and category slugs share /portfolio/[slug]; saving now rejects a
  slug already used on the other side instead of silently shadowing it.

Tooling/docs
- Lint: ignore scripts/legacy-prisma-seed.cjs, drop unused import.
- New docs/SEO.md; FEATURES, ARCHITECTURE (Drizzle instead of Prisma), admin
  spec and CLAUDE.md updated.
- Tests for all of the above (unit + integration); suite green.

# Architecture
## Stack
- Next.js (App Router)
- TypeScript
- next-intl
- Prisma + PostgreSQL
- Tailwind CSS
- Radix UI (via local primitives)
- framer-motion
- nodemailer
---
# Application Structure
## Public application
Localized public pages live under:
app/[locale]/(site)
Locale routing and configuration are defined in:
i18n/routing.ts
The public layout checks the maintenance status and redirects visitors to:
/coming-soon
when maintenance mode is enabled.
---
## Admin application
Admin pages are implemented under:
app/_admin
Internal admin routing is rewritten to:
app/admin-internal
Development alias routes also exist under:
app/root
Routing decisions and host/path-based rewrites are implemented in:
lib/admin-routing.ts
The `_admin` structure should be treated as the canonical admin source.
---
# Core Modules
Application logic lives primarily in `lib/*`.
Important modules include:
lib/portfolio.ts
Handles portfolio queries and localized mapping.
lib/app-config.ts
Provides application-level configuration values.
lib/media.ts
Handles media library queries and media bindings.
lib/mail.ts
Handles SMTP delivery via nodemailer.
These modules act as the primary server-side application layer.
---
# UI Layer
Shared UI primitives live in:
components/ui
These primitives wrap Radix UI components and define the shared design system.
Public site UI components live in:
components/site
components/layout
Admin UI components live in:
components/admin
components/dashboard
Shared primitives must always originate from `components/ui`.
Feature-level UI should reuse these primitives rather than reimplementing them.
---
# Persistence Layer
Database access is implemented using Prisma.
Prisma client lives in:
lib/prisma.ts
Configuration values are stored in the database via:
AppConfig
which acts as a key-value store for runtime configuration values.
Database access should always occur through server-side modules.
Client components must never access Prisma directly.
---
# Architectural Boundaries
The following boundaries must be respected:
- Client components must not access Prisma.
- Business logic must not live inside UI components.
- Shared UI must originate from `components/ui`.
- Public site UI belongs in `components/site`.
- Admin UI belongs in `components/admin` or `components/dashboard`.
- Server actions act as request entry points for form submissions.
- Server actions may call modules in `lib/*`.
Database queries should not be implemented directly inside route-level UI files.
---
# Request Flow Examples
## Contact submission
1. User submits the form on
app/[locale]/(site)/contact/page.tsx
2. Server action validates the input using Zod.
3. Email is sent through:
lib/mail.ts
5. The user is redirected to:
/success
or back to the form with an error state.
---
## Portfolio publishing
1. Admin edits a project form.
2. Server action validates categories, fields, sections, and assets.
3. Media selections are resolved via:
lib/media.ts
4. Project data, sections, assets, and media usage are persisted via Prisma.
5. Public and admin paths are revalidated.
---
# Canonical Sources
The following files should be treated as canonical sources for specific domains:
Routing
i18n/routing.ts
Admin routing
lib/admin-routing.ts
Database access (Drizzle)
lib/db/index.ts, lib/db/schema.ts
Application configuration
lib/app-config.ts
Portfolio logic
lib/portfolio.ts
Media handling
lib/media.ts (DB), lib/media-storage.ts (filesystem + content validation), lib/media-service.ts
SEO / metadata
lib/metadata.ts, lib/seo-settings.ts, lib/seo-report.ts, app/robots.ts, app/sitemap.ts (docs/SEO.md)
Admin session token (shared by middleware and server auth)
lib/admin-session-token.ts
---
# Proposed Future Improvements (Not Implemented)
These ideas are **not currently implemented** but may be introduced later:
- Split `app-config` concerns into smaller modules if additional domains are added.
- Introduce dedicated models instead of expanding the `AppConfig` key-value store.
- Introduce explicit service boundaries if the application grows significantly.ڑ
