/* ---------- Logo mark (3D animated emblem) ----------
A single transparent PNG cut from ice-ev.png. It idles in 3D: a slow turn on
Y, a bob that lifts and tilts on X, and a glow that breathes with the turn.
Because the art is transparent there is no card here — no rounded rim, no
panel shadow, no sheen sweep; the glow is a drop-shadow so it follows the
emblem's silhouette rather than a box.
The turn stays inside +/-30deg so the face is always toward the viewer, which
is why no back face (and no backface-visibility) is needed.
Sizes come from --logo-size, so the same markup serves nav, footer and hero.
