/* Login v2 (owner-approved AFTER, Alex 2026-09-28): the yellow/black restyle of the
   shared /login page (hosts and staff alike). Relies on host_v2.css's tokens (the
   --v2-* family) and the Outfit @font-face it declares — this sheet adds neither.
   Section 1 ("Login") of
   standard-designlab-preview-c5e57f3804.s3.us-east-1.amazonaws.com/canary/comparisons/latest.html.

   Dark only, no blur()/backdrop-filter (DS3 motion rule): the only glow is the
   decorative radial-gradient behind the mark, never a control. Every control is
   >= 44px. The single primary (yellow) control is "Sign in with STANDARD"; the
   password fallback's "Log in" is a quiet outlined button UNLESS the fallback is the
   page's only way in (.login-fallback--only), in which case it takes the yellow
   treatment instead — the page never shows two yellow actions at once. An error is
   words plus the existing role=alert, never a red/green paint (CAN-D5). */
