 * Not a retrofit layer — loaded on every page from Stage 2 onward.

 * Contains:
 * - the skip-to-content link (hidden until focused, first focusable
 *   element on every page)
 * - focus-visible baseline shared by anything not already covered in
 *   typography.css / nav.css / components.css
 *
 * Semantic landmarks (header/nav/main/footer), heading hierarchy, and
 * keyboard focus order are enforced in the HTML itself, not here —
 * this file only covers what CSS is responsible for.
