   Водопада — the menu book
   A hand-bound menu lying open on a walnut table: linen cover in forest
   green, aged ivory paper with grain and foxing, engraved rules, brass
   accents and a silk ribbon. Visual layer only — markup and behaviour
   come from js/script.js (renderMenu).
   Textures are tiny inline SVG noise tiles, rasterised once and cached.
