FieldSignalContext

Generic types:TModel

Field signal context - the "nervous system" of the dynamic form. Provided via FIELD_SIGNAL_CONTEXT injection token.

Gives mappers and components access to form state, values, and configuration. Container fields (Group, Array) create scoped contexts with nested forms.

The form property uses Angular's FieldTree which includes Subfields for type-safe child field access via bracket notation when TModel is a Record.
