/* Page chrome for /see-it-run/board/ and its translations.
 *
 * 🔴 CLASS SELECTORS ONLY, and neither home.css nor locales.css is loaded. The replay mounts
 * its own <header>, <main> and <section> inside #board-replay, and those two files style
 * bare `header`, `main`, `section` and `h2` (sticky headers, section padding, a narrow-phone
 * `header { flex-wrap }` rule), which would reach into the board. The replay scopes its own
 * theme under .board-replay-root; this file keeps the same promise from the page's side.
 *
 * The language-switch rules repeat the ones in locales.css for the same reason.
