Generates mobile login screens with phone/SMS verification, password auth, and social SSO options. The workflow forces you to read a checklist file first before building anything, which is a smart gate to keep you from shipping half-baked auth flows. Outputs a standalone HTML prototype at 375px viewport width with proper touch targets, labeled inputs (not just placeholders), password show/hide toggles, and loading/error states baked in. Honestly most useful as a starting point rather than production code, but it handles the fiddly bits like safe area insets and proper input keyboard types so you're not Googling those again.
