/* Open Vacancy Radar landing page.
   Palette mirrors the desktop app exactly (design-reference/HANDOFF.md): primary is a black/white
   inversion between themes, not a brand hue. The radar's glow, sweep, and highlight states use
   that same inversion, monochrome in both light and dark, the same way the real app is. Color
   only appears where the real app uses it too: ok/warn/danger status (verification, prep gaps).

   Theme: `[data-ovr]` on <html> is "dark" or "light", set by an inline blocking script (before
   first paint) from localStorage or `prefers-color-scheme`, and by the toggle in the top bar
   afterward. This matches the app's own Light/Dark/System model.

   Motion policy: every element renders in a finished, static state by default. All animation is
   declared inside `@media (prefers-reduced-motion: no-preference)`, so reduced-motion users get the
   static design as a real fallback. */
