   one. `revert` restores each element's natural display (inline for
   <span>, block for <p>/<div>, list-item for <li>) so the same .lang-en/
   .lang-th pair works on any tag without extra per-tag rules. */
/* Scoped to `body` (not a bare `.lang-th` selector) because `js/main.js`
   also toggles a same-named `lang-th` class onto <html> itself to switch
   the active language — an unscoped rule here would match <html class="lang-th">
