/* AWACS.AI shared component styles — dark rebrand 2026-06-29 (consultant/educator pivot).
   Loaded AFTER tokens.css + nav.css on the rebranded 6-section pages. Holds the base
   reset, layout container, buttons, cards, four-lane router, steps, proof strip, and
   footer so the new IA stays visually consistent without per-page CSS duplication.
   Legacy (non-rebranded) pages do NOT link this file. */
