/* ── Contact nudge — a small arrow that periodically points at the
   "contact" link. Absolutely positioned inside its own relative
   wrapper so it never occupies a flex slot in the nav — hidden it
   adds zero width and can't shift the other links, wipe in/out or
   not. The reveal uses a stepped timing function (chunky rather
   than silky) plus a film-grain overlay for a "grainy wipe" feel,
   reusing the same turbulence noise used on the project images. ── */
