/* static/css/home_redesign.css
 *
 * Home page redesign (Nov 2026). Loaded after home_style.css and only by
 * templates/home.html. The new markup uses "cv-" class names, so most of
 * home_style.css no longer applies to it; that file still styles the login,
 * sign-up and password overlays, the lightbox, the nav drawer and the
 * loading screen.
 *
 * Look: a technical-report page. Paper background, ink text, one water-blue
 * accent, serif headings, hairline rules instead of cards and shadows.
