/**
 * @file homestead-landing.css
 * @description Layout and components for the public Herrera Homestead site. Phone-first, no
 *   horizontal scroll at any width, visible focus states, and a full prefers-reduced-motion
 *   fallback. Reads every colour from homestead-theme-tokens.css, which must load first.
 *
 * @status Complete. Covers index.html and 404.html; both use the same header, footer and
 *   section primitives so new sections need no new CSS.
 * @issues None
 * @todo None
