/**
 * Branding Service
 *
 * Provides whitelabel-friendly branding values (app name, support emails,
 * asset paths, theme colors) with three-tier resolution:
 *
 *   defaults  <  env vars  <  extension override
 *
 * If nothing is set, Accounted defaults are returned — production behaviour
 * is unchanged. A whitelabel sets env vars (NEXT_PUBLIC_BRANDING_* for
 * client-readable, BRANDING_* for server-only) or registers a branding
 * extension via registerBrandingService().
 *
 * See WHITELABEL.md for the full env var reference and fork checklist.
