  beneficiaries, 3 donors, and WhatsApp log. All 14 API routes implemented across
  requests, donors, stats, and whatsapp-log. OpenClaw integration with OPENCLAW_SIMULATE
  toggle. UUID-based IDs. Full status machine (new → closed, 10 steps).

- Frontend (ehsan-poc): 8 pages fully implemented using all generated API hooks:
  Home (stats counters, 10-step workflow diagram), Request (form with eligibility
  result), Opportunities (card grid with progress bars), Donate (case summary +
  donor form), Admin (full data table with contextual action buttons), Track
  (10-step visual timeline in green), ThankYou (message form), WhatsApp Log
  (WhatsApp bubble preview + OpenClaw send button).

- Bilingual LanguageContext (AR/EN) with RTL/LTR toggle, localStorage persistence.
  EHSAN green palette (HSL 143), Tajawal font, fully responsive.
  TypeScript clean — zero errors.
