/* ================================================================
   SITE THEME — shared public-website design system
   Loaded on every public page after style.css / public-phase2.css.
   Centralizes navbar-solid behavior, logo link fix, page headers,
   section spacing, card/form/button system and responsive rules so
   no page needs its own header/footer/logo hacks.
   ================================================================ */

/* ===== LOGO LINK FIX =====
   The brand logo is rendered as <a class="logo">Arunalaya<span>.</span></a>
   on every public page. These rules guarantee:
   - correct brand color (white on transparent hero, charcoal on solid/scrolled)
   - NO browser-default blue link color
   - NO underline (including :hover and :visited)
   - the "." accent span is always gold
   Specificity is kept high enough to win over generic <a> defaults. */
