Generates complete Auth0 Advanced Custom Universal Login screens with proper branding and theming. This follows an 8-phase workflow that handles everything from CLI authentication through dev mode wiring, and knows to pull from auth0-acul-samples for modular component architecture when available (31 React screens catalogued) or fall back to SDK examples for single-file implementations. It enforces the reference hierarchy hard, which matters because the 68+ ACUL screens use different hook patterns and grabbing the wrong one breaks your auth flow. Supports both React and vanilla JS stacks, handles social login wiring, and won't let you proceed without a custom domain on your tenant since that's a hard ACUL requirement.
