GitHub/Google buttons on the login page pointed at providers that may not be configured in Supabase, dead-ending in an error. Add NEXT_PUBLIC_OAUTH_GITHUB / NEXT_PUBLIC_OAUTH_GOOGLE (opt-in, "true" to show); a provider button renders only when enabled and the whole social block is hidden when neither is. Pure resolveOAuthProviders helper is unit-tested; flags documented in .env.example and DEPLOYMENT.md.

// client component and needs the value in the browser bundle.
