/**
 * Variant CSS: faq--categorized-tabs
 *
 * Static category tab row above a grouped <details> Q/A list. The active tab is
 * pre-set (no JS) so the section stays fully editable in Gutenberg; tabs read as
 * navigation chrome that organises a large FAQ thematically. Distinct from the
 * plain accordion, single column and 2-col grid. Text stays --ink (polarity-aware);
 * kicker, active tab, em and the +/- toggle take --accent. Part of the `faq` role.
