// Build-time feature flags shared across Entropy Softworks apps.
//
// Expo inlines `EXPO_PUBLIC_*` env vars at bundle time, so these resolve to
// constants in each app's build. Both default OFF-state when unset:
//
//   EXPO_PUBLIC_DISABLE_BRANDING  default false → Entropy branding shown.
//     Self-hosters may set "true" to strip Entropy logo / boot splash /
//     "An Entropy Softworks product" byline + entropy-related legal content.
//     It does NOT touch the product's own logo/branding. SaaS ships "false".
//
//   EXPO_PUBLIC_ENABLE_LICENSING  default false → no licensing gate active.
//     SaaS production ships "true" and a separate app supplies the actual
//     licensing/subscription integration. Self-hosters leave it off; the gate
//     wiring is present everywhere either way.
//
// INVARIANT: licensing requires Entropy branding. Licensing is only ever used
// by Entropy's own SaaS deployments, which always carry the company branding
// and legal content — so ENABLE_LICENSING is coerced off (with a warning)
// whenever DISABLE_BRANDING is set. There is no valid unbranded+licensed
// configuration.
