Flutter building forms

Ship forms with Form / FormField on Flutter 3.47+. Do not add GetX, flutter_form_builder, or Expo/RN form patterns. If this repo already has a Form wrapper, shared validators, ThemeData.inputDecorationTheme, or an AutofillGroup around auth, extend those. If widgets already read a house ThemeExtension or *Pressable, style fields from that system — do not drop a stock Material decoration theme onto a branded surface.

Scroll the form with the project's existing ListView / CustomScrollView. A bare Column under the keyboard will overflow.
