/* ==========================================================================
   sv-portal.css — student portal (sign-in + signed-in landing).
   Phase 2 of the Y2 student portal.

   Namespaced sv- like the Strategy Vault, and loaded alongside css/sv.css,
   which owns the --sv-* tokens and the shared breadcrumb strip. Nothing here
   redefines a token; if a colour needs changing it changes in sv.css and both
   surfaces follow.

   Contrast, measured against the AA 4.5:1 floor for body text:
     ink   #14264C on paper  #FBFAF6   14.25:1
     ink   #14264C on pencil #F5B91E    8.39:1   (primary button)
     soft  #3D4E75 on paper  #FBFAF6    7.90:1   (help text)
     red   #B3413A on paper  #FBFAF6    5.38:1   (errors)
     green #2E7D4F on paper  #FBFAF6    4.83:1   (confirmations)
     mist  #D9DEEA on ink    #14264C   11.04:1   (header)
   Re-measure before changing any hex.
