   Forced Migration — what only this app uses
   -----------------------------------------------------------------------------
   Tokens and the shared components are in projects/static/projects/tools/tool.css
   (linked first by projects/_tool_base.html); the design direction is
   docs/unga-design.md. Plain CSS, linked with {% static_v %}.

   Event-type colours: the owner's red, blue, green and amber, the last three
   tuned to pass the dataviz palette validator (chroma floor, lightness band) on
   both surfaces, each mode with its own steps. Light: #f94144 #1d74b7 #2fa37f
   #d9a521; dark: #f94144 #3b82c4 #2fa37f #b8860b. Re-validated on the token
   surfaces (2026-10-02: light --pe-surface, dark --pe-surface): all checks
   pass; the amber's sub-3:1 contrast in light mode (2.2:1) is relieved by the
   labels on every chip and the Cases table. They mark the same type in every
   view, and nothing else is drawn in them.
