/* Foul Flock - map chrome on top of Pico CSS (classless, vendored at
   assets/pico.classless.min.css).

   Division of labor:
   - Pico owns base typography, links, buttons, form controls, details,
     and the light/dark switch (prefers-color-scheme).
   - This file owns the theme tokens (fonts + colors, set via --pico-*
     variables below) and the map chrome: topbar, legend, detail panel,
     modal, and MapLibre fixes.

   Color system, kept minimal: one interactive accent (deep teal) via
   Pico's primary, neutral ink/paper from Pico, and status hues reserved
   for meaning on the map (red flagged, blue clear, brown possibly-exempt,
   purple law states, grey reviewed). All pairs meet WCAG 2.1 AA; asserted
   by axe in tests/a11y.spec.js. */
