Twenty account components: SettingsList, OptionCycler, KeyBindings, ControllerMap, ProfileCard, CharacterCreator, LoginForm, PasswordGrid, SessionList, LanguagePicker, PalettePicker, VolumeMixer, DifficultySelect, AccessibilityOptions, AccountSwitcher, PlayerSelect, TwoFactor, About, PatchNotes and FeedbackForm. The components never check credentials, and no secret reaches the log: LoginForm reports Submitted and the caller counts Failures; each new failure clears the password, refocuses it, shakes the form and names no field. TwoFactor builds on input.PinInput and drains an epoch-aligned period bar. PalettePicker draws each tile in its own palette on a pixel.Pad grid. pixel.Settings.Reduce stills motion like the system preference, the micro font gains '?', display.Face draws avatar faces anywhere, and input.PinInput pastes on Cmd+V as native hosts send it.
