   Carafe & Gilt — home page layout
   Masthead, hero (thesis + search action), category pills, "recently added"
   grid and footer. Loaded after tokens.css and card.css. The recipe card
   itself lives in card.css (shared with the future Browse page).
   Masthead/footer intentionally mirror the recipe page (recipe.css) so the
   home page reads as the same site.
