Form field composition: Field, FieldControl, FieldLabel, FieldDescription, FieldError. Auto-wires accessibility: FieldControl (a Slot around any control) receives a generated id, aria-describedby pointing at the description and error, and aria-invalid; the label targets the control automatically. invalid/disabled props drive data attributes, label color and dimming. orientation switches vertical (default) and horizontal (label-left, e.g. switch rows).
