/* =========================================================================
 * router-info.css — styles for the curated route overview page (router-info.php)
 *
 * Scope: every rule is prefixed with `.router-info-page` (the <body> class)
 * so this file never restyles the legacy route-detail.php page, which reuses
 * the same .route-* class names. New, page-specific components use the .ri-
 * prefix.
 *
 * Breakpoints (explicit, self-verified):
 *   - desktop  : > 1024px   -> two-column grid, left wide / right 360px rail
 *   - tablet   : 768–1024px  -> single column, sidebar stacks below main
 *   - mobile   : < 768px     -> full width, tightened padding, smaller hero
 * ========================================================================= */
