/*
  AMI AI Suite — Cards Portal Landing (skeleton CSS) — Plan 6.5 prompt 05 (A3).

  Depends on:
    core_platform/shared/css/hex-design-system.css (tokens + .data-xl, .body-*)
    core_platform/shared/css/hex-components.css   (.glass-panel, .btn-hex, .angled-panel)

  Tokens used (each MUST exist in hex-design-system.css per B3 lock):
    --panel-bg, --border-color, --border-light,
    --text-main, --text-muted, --text-dim,
    --hex-blue, --hex-glow,
    --accent-green, --accent-orange, --accent-red,
    --font-mono

  NO bespoke tokens. NO :root redefinition.
