/* internal.css — styling for the internal.drpaulk.ai portal.
 *
 * Layers on top of styles.css + theme.css (loaded first). Reuses the shared
 * Wake glass theme tokens (--wake-teal, --card-bg, --text-light, …) so the
 * internal portal matches the public drpaulk.ai look exactly; only the
 * portal-specific pieces (the "Internal" badge, the account control, the
 * welcome hero, and the area cards) are defined here.
