/* =========================================================================
   EP3 home page — page-level composition styles.
   Loaded only on site/index.html. All tokens from webshield-navy.css.

   Mirrors the per-page CSS pattern from sibling webshield-dev/website
   (webshield-home.css) but with EP3-warm rhythm and image-led cards.

   Component styles for the broader directory pages (full accelerator card,
   member card with bio modal, affiliate tile with search) live in their
   own per-component files and ship at later steps. The compact card
   variants below are home-only.

   Step 4 of the redesign per docs/brief-website.md §11.1.
