   Simple App — "Access Panel" design
   A small system for registering, logging in, and viewing who has access.
   Palette leans on a deep teal ("access granted") against a cool slate
   backdrop, with a monospace utility face for session/status data —
   echoing the credential-and-clearance subject matter of the app itself.
