/* BAUSTK Cafeteria — "linen and basil": one light theme for everyone (no dark mode).
   A warm linen page, white surfaces, a deep basil green for the brand, buttons
   and the announcement bar (its only accent), warm charcoal text. Serif
   headings (Cormorant Garamond, self-hosted) over the system sans, square
   corners, a line grid of dish tiles with a spotlight behind each picture.
   Colours are hex only. Contrast is checked by tools/contrast_check.
   No external assets: the server's CSP is default-src 'self'. */
