/* ==========================================================================
   Landing page (index.html). Builds on style.css for the header, footer,
   .container and .app-store-btn.

   Look: the app's warm cream page, Plated coral, and the fox and recipe-pile
   art from the App Store header. Sections alternate cream / white / coral /
   ink so the page has rhythm instead of one long white sheet.

   Values follow the landing-page-design skill: named text styles on the
   Tailwind type scale, the spacing tokens below, Tailwind radii, flat fills.
