   Shares its token names with styles.css on purpose: the same `--bg`,
   `--surface`, `--separator`, `--label`, `--accent` and `--ease`. That is what
   makes these pages feel like part of the translator rather than a bolted-on
   document, and it means the theme toggle behaves identically on all three.
