Architecture documentation was moved to the Project Bible:

UI design-code integration

core now serves UI theme assets from ui-design-code at runtime:

• CSS: /ui-design/static/css/theme.css
• JS: /ui-design/static/js/app.js

Path resolution order for ui-design-code:

1. UI_DESIGN_CODE_DIR env var
2. ./tools/ui-design-code
3. ../ui-design-code

This lets UI updates in ui-design-code appear in core without copying files.
