/* base.css — shared design tokens and global chrome for all templates.

 * standard template family: reset, tokens, body defaults, nav (desktop +
 * mobile + hamburger), footer link colours, skip link, reduced-motion.
 *
 * The homepage (body.home-v2) intentionally keeps its own inline tokens
 * and coral nav-CTA override; its later-loaded home-v2.css continues to
 * win where the designs differ.
 *
 * Maintained by scripts/sync_shared.py, which links this file into every
