/* ============================================================
   CATEGORY-PAGE.CSS
   Shared stylesheet for the 4 AI-category pages (career-ai.php,
   marketplace-social-ai.php, personal-ai.php, business-ai.php).
   One file, one set of components (includes/sections/category-*.php) -
   the 4 pages differ only in the data they're fed
   (includes/data/category-pages.php), not in markup or CSS, so
   they stay pixel-identical by construction.

   Reuses every token already defined in style.css (:root vars,
   .container, .section-*, .cta-*, .reveal-child, .stat-*) and the
   exact .final-cta-* classes from sections-v2.css for Section 9 -
   only the components genuinely new to these pages (hero visual,
   agent cards, why cards, featured rows, scenario cards, feature
   tiles, FAQ accordion) are defined here.

   Palette discipline: no per-category hue. Every accent on these
   pages is var(--clr-primary) or var(--clr-dark) - the brief for
   this page family explicitly restricts color to brand primary +
   ink, unlike the homepage's 4-color category system.
