/* race.css — styles for the isolated typing-race page (/{lang}/typing-race).
   Self-contained: uses the site theme CSS variables so it adapts to every
   theme, and defines a couple of race-only accents with fallbacks. No
   dependency on the core typing engine / tf-widget. Tuned compact so the
   whole race (lanes + text) fits one screen without scrolling.

   THEME VAR NAMING (important): text/border tokens are `--color-ink` and
   `--color-line` (Tailwind-v4 style) — there are NO bare `--ink`/`--line`
   aliases, so using those silently drops the rule (missing borders/text).
   Surfaces/accents DO have bare aliases: --surface/--surface2/--surface3,
   --primary, --muted, --muted-dark, --yellow, --orange, --bg. */
