/* ===== FAQ page (faq-aqua.html) ===== */
/* Shares style-aqua.css's design language -- these rules only add the
   page-specific chrome. The accordion itself reuses .faq-section /
   .faq-glow / .faq-card / .faq-badge / .faq-heading / .faq-list /
   .faq-item* exactly as already built (index.html / integrations-aqua.html
   / automations-aqua.html), unmodified -- one .faq-card per category
   instead of the single mini-list those pages embed. New "faqp-" prefixed
   classes below are page-specific chrome that doesn't exist elsewhere
   (nav-without-hero-video band, hero heading/search, category tabs). */

/* ----- Hero -----
   Built as one photo hero (same structural pattern as about/contact/
   automations etc): full-bleed image + scrim, nav sitting flush on top
   of it, then the heading/search/category-pills content below the nav,
   all layered above the image via z-index. Nothing here lives in a
   separate light-bg band anymore -- the pills are now part of the hero
   itself, styled as frosted glass to sit on the photo instead of the
   solid-white pills the old light section used. */
