Form tokens

Shared form-control utilities — neutral focus ramp, flat surfaces, explicit error borders.

Foundations · fixture-only

Primitive-aligned custom controls

Compose formControlSurface + formControlBorder() on bespoke inputs so focus matches Input/Select.

Workshop: SearchableSelect trigger, inline editors, filter popovers with text fields.

Fixture data only — behaviour matches production chrome

Error state borders

Pass error to formControlBorder(true) or the error prop on Input — danger ring only on invalid fields.

Workshop: FormField validation on create/edit dialogs.
Avoid: Brand-colored focus on invalid fields — error uses danger tokens only.

Fixture data only — behaviour matches production chrome

Duration formatting helper

formatDurationMs for consistent tool-step and run-time labels in agent and ops surfaces.

Workshop: Agent transcript tool steps, workflow run timelines.
