+## 2026-07-28 - Interactive presentation and portfolio pass
+
+- Added a keyboard-operable four-stage project-chain illustration to the
+  public landing page. Selection, source governance, PyTorch analysis and QA
+  evidence each change the explanatory state and map treatment.
+- Added restrained route, scan, evidence and map-depth motion. Every animation
+  and transition is disabled under `prefers-reduced-motion`.
+- Generated two original, text-free GeoIntel campaign images: a Belgian
+  land/sea GeoAI hero and a building-detection/QA orthophoto composition. The
+  assets are stored in `frontend/public/portfolio` for reuse.
+- Captured repository-owned portfolio screenshots for the landing hero,
+  interactive project story, map workbench, quality workbench and mobile
+  landing experience in `docs/assets/portfolio`.
+- Replaced the legacy README with a product-led overview, visual tour,
+  architecture diagram, governed AI/CUDA behavior, setup, verification,
+  deployment and documentation map.
+- Browser checks confirmed the tab interaction, the PyTorch stage content and
+  a 390 px layout without horizontal overflow.
+
+Verified in this pass:
+
+- `npm run typecheck`
+- `npm run test:unit -- --maxWorkers=1 --reporter=verbose` (`45 passed`)
+- `npm run build` (`1892 modules transformed`, production build passed)
