/**
 * Route Map component — /routes/ hero interactive widget.
 *
 * LIGHT editorial treatment — matches the rest of the site (ivory/paper
 * surfaces, ink text, navy accent, brass eyebrows, Fraunces display) and the
 * "Route Legs" planner card from the Jet Supply CMS map prototype. Replaces the
 * earlier dark band, which read as foreign against the light routes page.
 *
 * All colour/type/space values come from tokens.css — never hardcoded hex.
 * Enqueued conditionally (route archive only) — NOT @import'd into main.css (D-26).
 *
 * BEM: .route-map (block), .route-map__el (element), .route-map--mod (modifier).
