/* Regmap — marketing site, v2.
   Conviction: "cartographer's ledger" — the regulatory atlas. Sibling of the
   verdict-site evidence camera: same skeleton (mono ledger labels, hairline
   rules, stop-motion steps() frames, three-depth parallax, dark pledge band),
   but brighter ground and emerald/amber authority in place of cobalt/orange
   attack. Emerald = covered & cited; amber = the gap. Motion ticks in discrete
   frames; never a glide. All decorative motion double-guarded:
   @supports + prefers-reduced-motion. */
