/*
 * Phase 7 of the redesign (2026-10-30): the home page (home-page.php), an
 * author (author-page.php), the authors archive (authors-page.php), the
 * service pages (service-page.php), the 404 (notfound-page.php). Sources:
 * design/projects/home/proto/home.html, design/projects/pages/proto/pages.html,
 * DESIGN.md "Home", "Authors and service pages". The cards are css/card.css.
 * Scoped to .hm / .pg so the old bare rules of style.css stay out.
