/* NOCTULE's own styling. Deliberately NOT ../style.css, which is themed ink-on-paper
   for Supply Lines; a player arriving from the App Store listing should land on
   something that looks like the game they just tapped.

   The palette is lifted from the app, not approximated:
     background  #05030A          lib/ui/*.dart, the cave's black
     ink         hsl(280 30% 92%) PixelTuning.hue 280, the "VIOLET" default
     dim         hsl(280 30% 55%)
     faint       hsl(280 30% 30%)
     pulse       hsl(305 85% 62%) PixelTuning.pulseHue 305, "MAGENTA" — the lit edge
   Two brightness steps do the ranking, as on the board screen; the saturated hue is
   reserved for things that are *lit*, which here means links.

   Dark only, on purpose. This is a game about being in the dark, and a light-mode
   variant would be the one screen in the whole product that is not. Every colour is
   painted explicitly rather than inherited, so a light-mode browser still gets the cave.

   No web fonts, no build step, no external requests. These pages have to keep loading
   for an App Store reviewer years from now; every moving part removed is one that
   cannot fail. */
