       cc-auth.html CSS tokens  (C-05 / L-09 documentation)
       ─────────────────────────────────────────────────────────────────────
       This form uses its own :root token set — not .hhp-shell scoped.
       Most values match hhp.css defaults. Deliberate divergences:
         --green (#059669 deeper emerald)  vs  hhp.css --success (#10B981 teal)
         --red   (#DC2626 classic red)     vs  hhp.css --danger  (#EF4444 pink-red)
       These are intentional: the guest-facing form benefits from more
       conventional success/error colors. If alignment is needed in future,
       update these two values.

       FORM-SPECIFIC tokens (no hhp.css equivalent):
         --teal3:    #0F1E2E  — dark teal for vcard gradient background
         --bord2:    rgba(14,165,233,.40) — stronger border for emphasis
         --p2:       #f0f7fd  — tinted input background (form UX pattern)
         --chip-grad: gold gradient for virtual card chip
         --amber:    #9A6400  — defined but currently unused; keep for future

       CANONICAL ALIASES (mirror hhp.css semantic names):
         --primary = --teal (same value: #0EA5E9)
         --primary-hover = --teal2 (same value: #0284C7)
         --text-muted = --muted (same value: #5A6A7A)
         --text-subtle = --mut2 (same value: #93A3B0)

       When the PMS app frames this page inline it passes `embed=1`; cc-auth.js

       the guest only needs the card fields + save action. Strip the standalone
       chrome — dev bar, hotel header, 3-step progress, virtual-card graphic,
       the security-badge row and the "never stored in plain text" intro note,
       and the footer — and trim the outer margins so the form sits flush in the
       iframe with no dead space. The subtle secured caption in the step sub-head
       ("Saved securely on file — encrypted end-to-end") is the one reassurance
       we keep. Presentational only; gated entirely behind `body.embed`, so the
       standalone (emailed-link) flow is visually unchanged. The parent iframe
       resize measures content height, so this leaner layout is what it reports. */
