   css/base.css — design tokens + reusable components for every page
   --------------------------------------------------------------------------
   Loaded by index.html and stats.html before layout.css / game.css.
   Owner: frontend-shell-agent. The game views (css/game.css) build on these
   tokens and utility classes, so names here are a contract — do not rename.

   Look: "a touch of" the Pokémon Scarlet/Violet menu — dark translucent navy
   panels floating on a soft landscape gradient, white text, a single muted
   Pokéball-red accent for the selected row / primary action (phase 2,
   DECISIONS.md 45 — the phase-1 yellow is gone), green rounded HP bars and
   type-coloured badges. Modern and readable, not a pixel-retro UI.
