/* Contact — dark surface, layered on index.css tokens (contact-guided-v1 · dark 2026-07-08).
   Loads AFTER index.css; consumes its :root tokens (--bg,--ink,--ink2,--muted,--cyan,--line,
   --line2,--line3,--panel,--panel2,--warn). Chrome (nav/footer/body) comes from index.css;
   this sheet styles the guided form surface only. Every fg/bg pair meets WCAG 2.2 AA. */

/* ambient surface (2026-07-09) — mirrors index.css's hero washes (--bg2 navy gradient +
   faint cyan radials) so contact reads as the same textured dark system as the homepage.
   All washes darken toward or match --bg (#0A0B0D): --bg2/#0B1F3A sits in the same
   luminance band and the cyan radials cap at 6% alpha — every AA pair verified
   against --bg still passes. */
