/* ============================================================
   Noe Harness — auth stylesheet (login.html)

   Mirrors the tokens from css/styles.css (and template.html) so
   the auth screen reads as one brand: near-black surfaces, IBM
   Plex type, 1px hairlines, sharp corners, inverse selection,
   restrained mono labels (ADR-0007). If the shared palette
   changes, update this file too.

   Section map:
     tokens / base / stage / card / brand rail / form panel /
     submit + foot / back link / toast / responsive / reduced motion
