CNGX_FORM_FIELD_CONTROL

Description#

Injection token provided by controls inside a cngx-form-field (or any other host that consumes the same contract). The form-field presenter discovers the active control through a signal content query on this token and projects field-level state from the five contract surfaces: focused / empty drive the .cngx-field--focused / .cngx-field--empty host classes, disabled / errorState widen .cngx-field--disabled / .cngx-field--error to field-OR-control, and id becomes the label's for-target. Per-control ARIA attributes remain the control's own read via createFieldControlAria (forms side) or CNGX_FORM_FIELD_HOST (common side) - the discovery query never writes onto the control.

When several descendants provide the token (a nested composite wrapping inner controls), the first provider in content order wins - the outer composite resolves before its inner controls.

@cngx/forms/field re-exports this constant so the existing import { CNGX_FORM_FIELD_CONTROL } from '@cngx/forms/field' import path keeps working unchanged.
