   SHARED AUTH LAYOUT
   Loaded by: base_account.html for every page under /templates/account/
              (auth, forgot_password, set_password, password_reset_*,
               new_customer, suspended, verify)

   Architecture
   ------------
   All structure, spacing, typography, components — defined ONCE here using
   --auth-* tokens. Defaults are Gumo (navy card + gold accent).
   Brand-specific overrides live in:
       static/css/whitelabel/<brand>/auth.css
   which only re-declare the tokens (no layout rules). This keeps the three
   brand files from drifting out of sync, as they did before consolidation.

   Token cheat-sheet
   -----------------
   --auth-page-bg          page background (behind the card)
   --auth-card-bg          the hero card
   --auth-card-border      border colour for the card (transparent = none)
   --auth-text-primary     primary text on the card
   --auth-text-muted       secondary text on the card
   --auth-text-subtle      tertiary / disclaimer text on the card
   --auth-accent           brand accent — CTA button, active tab, focus ring
   --auth-accent-hover     hover state for accent-filled elements
   --auth-accent-contrast  text colour laid on top of --auth-accent
   --auth-accent-shadow           glow under accent buttons (rgba or var)
   --auth-accent-shadow-strong    stronger glow on hover
   --auth-accent-focus-ring       outer ring on focused inputs (rgba)
   --auth-input-bg         form field background
   --auth-input-text       form field text colour
   --auth-border-on-card   subtle dividers / checkbox borders on dark card
   --auth-decor-rgb-1      background radial #1 — comma-separated r,g,b
   --auth-decor-rgb-2      background radial #2 — comma-separated r,g,b
   --auth-shadow-card      card drop-shadow
