/*
 * «Настройки» — design_handoff_settings (set-sheet.jsx is the layout's source
 * of truth). Colours come from the IA tokens in ia.css; §6 of the handoff
 * added the ones this page needed next to them.
 *
 * `--ia-primary` is the prototype's `brand` in BOTH themes (#2489c5 light,
 * #63b4e4 dark), where `--ia-brand` stays #2489c5 in dark as well — so the
 * switch, the tab underline and the holiday cells use `--ia-primary`.
 *
 * NARROW IS A CONTAINER WIDTH, not a viewport width: the sidebar decides how
 * much of a 1024px screen the page actually gets, and the rows only care
 * about that. Same approach as tasks.css.
