/* ──────────────────────────────────────────────────────────────────────
   Auth pages — Linear-grounded, `.auth-v2` scope.

   Shell `auth/auth_base.html` (extends base_minimal) owns the split frame;
   child templates fill the form column. Quiet split: a calm dark brand
   panel (lg+) + a clean form column. No grain, no glow gradients, no
   decorative FA glyphs, no stock testimonial — hairlines + restraint.
   The brand panel carries a faint grid texture and an illustrative
   product vignette (sample ops rows + stat tiles) so the space reads as
   the product, not as a void.

   Tokens come from the GLOBAL design-variables.css (loaded by
   base_minimal), so the same palette as the rest of the app.
