/* ============================================================
   Tenant split login layout (P10A / DEMO-008 follow-up).
   Two columns: a light form panel (left, ~41%) and full-height
   tenant hero photography (right, ~59%). Entirely scoped under
   .ot-split, which only tenant contexts get (see login.ftl) - the
   base openthings theme never has this class, so its markup/CSS
   above is untouched.

   The form panel deliberately keeps the shared :root light tokens
   (--background/--surface/--ink/--muted from the top of this file)
   rather than adopting a tenant's dark brand.css palette: near-black
   ink on a near-white surface is what gets WCAG AA text contrast
   "for free" (house rule: no washed-out grey). Each variant.css only
   overrides --accent/--accent-hover/--accent-glow/--sidebar (for
   the button + focus ring) and a very light background tint, so the
   three panels stay visually distinct without sacrificing contrast.
