/* =========================================================
   SOMENTRAV — page de connexion
   Ported from the owner's approved example (login_example.zip).

   The layout is ordinary responsive flow — nothing is transform-scaled —
   and THE PAGE NEVER SCROLLS. Every vertical gap and the logo take a vh
   component in their clamp(), so on a short viewport the air shrinks
   before the content ever reaches the edge; below 620px of height the
   discipline pillars (context, not function) are dropped, as on phones.
   The vh clamps are budgeted for the shortest laptop (768px tall) WITH
   the pillars visible; verified by measuring the column at 800, 768,
   900, 1080 and 1440 of height.

   The only motion is on the photo itself: the workshop's lamps stutter on
   like real fluorescent tubes, then the cars' optics glow. Everything is
   keyframed from load; prefers-reduced-motion switches it all off.

   THEMES: the example ships a dark file and a light file; here they are one
   markup and two token sets. Base tokens are DARK (the agreed design);
   [data-theme] and prefers-color-scheme pick the set. The CTA stays the
   same blue in both themes on the owner's earlier rule — the light example
   had it orange, normalised here; one word restores it.
