/**
 * Consent + Gateway Design-Language Themes
 *
 * Two CSS-custom-property token sets shared by the new consent screen and
 * the (future) migrated OAuth Gateway consent. The themes match the screens
 * Peter approved for Hardware World:
 *
 * - `light` → paper background, dark on light, serif headline (Peter's mockup).
 * - `dark`  → glassy dark modal, soft halo backdrop (OAuth Gateway aesthetic).
 *
 * Components consume these tokens through Shadow DOM CSS (`var(--cs-*)`).
 * Org branding flows through `surfaceAccent` / `surfaceAccentText` so the
 * primary button can adopt operator brand color while the rest of the
 * surface stays in the chosen theme.
 *
 * The amber `HIGHER RISK` chip token is fixed across themes so the visual
 * stays recognizable regardless of org branding.
