/*
 * site.css: the only stylesheet for theolivegarden.co.uk.
 *
 * Sections, in order:
 *   1. Tokens        colours, fonts, spacing (custom properties)
 *   2. Fonts         @font-face for self-hosted Montserrat
 *   3. Base          reset and element defaults
 *   4. Layout        page wrapper, content column
 *   5. Components    one block per component: "=== Component: <name> ==="
 *   6. Pages         rare page-specific rules: "=== Page: <path> ==="
 *   7. Utilities     a handful of helpers
 *
 * Breakpoints (from the original app4clean theme; media queries can't use custom properties):
 *   mobile-small  ≤ 460px   (logo shrinks, home tiles stack to one column)
 *   mobile/tablet ≤ 768px   (hamburger menu, smaller type, home tiles 2 + 1)
 *   desktop       ≥ 769px
 *
 * Editing: change tokens to restyle the site; add new components as new blocks;
 * add modifier classes (.trio__tile--order) instead of changing a component for one page.
