/* Admin UI Foundation — the admin's one stylesheet for shell, page structure and common components.
 * No framework, no external font: tokens below, element defaults wrapped in :where() (zero specificity, so any class wins),
 * components as plain classes. editor.css (block editor, rich text, picker) builds on the same tokens.
 * Layout: topbar + sidebar (≥ 1024px) / drawer (< 1024px). Contents: page-header → (tabs) → sections/cards/tables. */
