Login with OAuth providers

Provider-first sign-in — Google, GitHub, and Apple buttons above an email fallback. Do: Treat the provider buttons as the primary path; keep the email form below the rule as a fallback, not the headline. Don't: Give the email field equal visual weight to the provider buttons when most users have a provider account. Do: Keep provider marks as their official inlined artwork, with GitHub and Apple taking currentColor so they invert correctly in Dusk. Don't: Restyle a provider mark to match your palette — that breaks the brand guidelines you agree to by using their sign-in. Use signup-social when this is account creation, not sign-in — signup-social also leads with OAuth providers. Use login when you store first-party passwords and don't want a provider-first order at all. Use login-minimal when you don't have OAuth providers configured and just need a single email field.
