 * Connect the Thoughts — shared arcade UI components.
 *
 * CANONICAL SOURCE. Edit only here (connectthethoughts/shared/), then run
 *   node scripts/sync-shared.mjs
 * to vend byte-identical copies into each game repo. `--check` flags drift.
 *
 * Token-driven via --accent. Per the arcade cohesion contract (tokens.css,
 * shared/README.md), games do NOT override --accent: there is ONE brand accent
 * (teal) across all games, so the chrome AND these components stay consistent.
 * Per-game identity lives on the homepage cards (data-tone) and in each game's
 * own board/illustration CSS — not in --accent. Text that sits ON the accent
 * uses --on-accent (white in light mode; a dark value in dark mode, set in
 * tokens.css — the dark teal accent needs dark on-accent text).
