/* ================= TRADE LANE — CRITICAL CSS =================
 * Everything needed for first paint above the fold on the 15
 * trade landing pages (hero -> service-also-trades -> booking-
 * showcase -> cta-section -> s360-faq -> explore-more).
 *
 * Built from the trade source (css/critical.css + global.css +
 * components/crg-banner.css), trimmed per TRADE-LANE-PLAN.md's
 * trim rule: coverage UNION interaction-states UNION media
 * queries UNION JS-toggled classes. Zero lines copied from Lane
 * A's home-critical.css / inner-critical.css.
 *
 * Colour: every raw value replaced with a css/tokens.css token
 * per BRIEF-LANE-B-T1-FOUNDATION.md's substitution table.
 * Transparency on TEXT removed entirely (full-strength token).
 * Transparency on backgrounds/borders/overlays/shadows kept,
 * expressed as color-mix().
 *
 * Load as: <link rel="stylesheet" href="trade/css/critical.css">
