/* ===========================================================================
   Relay: Instagram auto-reply guide (trymadar.co/service/instagram-auto-reply/).
   Follows the Relay brand contract (design-systems/madar-service/DESIGN.md):
   near-black canvas, warm off-white type, ONE coral accent, dark only,
   no gradients, one shadow (the thread panel). Rules below are taken from
   service/service.css so the two pages read as one product; the extra
   components (breadcrumb, tool rows, comparison, questions) follow the same
   tokens. Served from the Car Evaluator project: strict CSP, no inline styles.
