/* ============================================================
   landing.css — SECTION LANDING PAGE COMPONENTS
   Load this ONLY on section index pages (/ai-search/, /optimization/,
   etc.), after style.css — exactly like home.css on the homepage.

   Every selector is namespaced .lp-* (or scoped under .lp) so
   nothing here can collide with the shared components in style.css.
   All color / type / spacing reads from the existing :root tokens,
   so these pages re-theme (light/dark) with the rest of the site.

   Components:
     .lp-hero    — gradient-wash hero with quick-start pills
     .lp-group   — section cluster (head + sub + grid/rows)
     .lp-card    — routing card (icon, title, one-liner, arrow)
     .lp-card--feature — full-width cornerstone card
     .lp-rows    — compact scannable row list (engine guides)
     .lp-next    — "next section" hand-off band
   ============================================================ */
