/*
 * Phone and tablet layout (added 2026-10-25, not a legacy port).
 * Every rule sits inside a media query: from 1120px up the legacy fixed 1100px layout of style.css renders unchanged
 * (the parity suite screenshots at 1280px). The markup is the legacy one; js/responsive.js only adds the menu toggle,
 * so without JS the menu simply stays expanded.
 * Colours are sampled from the legacy images: menu-even/odd/hover.png, bg-1.png, bg-wrapper-1.png, line-1.jpg.
