 * Critical above-fold CSS — render-blocking, loaded before the main bundle.
 * Prevents two FOUC issues:
 *   1. The skip-link briefly appearing at the top of the page before the
 *      main stylesheet positions it off-screen.
 *   2. `.reveal` elements popping in when the IntersectionObserver fires
 *      after first paint.
 * Keep this file minimal — only first-paint essentials.
