/*
 * site.css: the only stylesheet for crumbsdiner.co.uk.
 *
 * Sections, in order:
 *   1. Tokens        colours, fonts, spacing (custom properties)
 *   2. Fonts         @font-face for self-hosted fonts
 *   3. Base          reset and element defaults
 *   4. Layout        container
 *   5. Components    one block per component: "=== Component: <name> ==="
 *   6. Pages         rare page-specific rules: "=== Page: <path> ==="
 *   7. Utilities     a handful of helpers
 *
 * Breakpoints (the original Elementor ones; media queries can't use custom properties):
 *   mobile  ≤ 767px    tablet 768px–1024px    desktop ≥ 1025px
 *   The main nav collapses to the burger at ≤ 767px (Elementor "dropdown: mobile").
 *
 * Editing: change tokens to restyle the site; add new components as new blocks;
 * add modifier classes (.split--accent) instead of changing a component for one page.
