/* 設定 — the settings screen (settings round, 2026-09-29).

 * A modal <dialog> (settings/settingsPanel.js). On a phone it is a full page:
 * the category list, then one category per page with a way back. From 768 px
 * it is a centred panel with the list as a sidebar beside the page. Every
 * control is a native input inside a fieldset; the cards below only dress
 * them. Sizes come from the type tokens, so the reading-size preference
 * applies here too.
