Staff sign-in
Sign in with your Gmail. After login you land on Dashboard with the sticky staff menu (Onboard, Folding, Sales, Learn AI, Ops, More…). No passcode.
Research-use company only. Not a medical device. Staff region only.
Flow: Google proves the address → we check it against the allowlist → session cookie.
Local dev fallback (STAFF_DEV_LOGIN). Production uses Google only.
