Tab
Source-backed Tab observing label at the next frame cutoff. Sources remain caller-owned; compatible nodes retain editing, focus, and scrolling state. Literal arguments keep their existing contracts. Equal source values do not re-evaluate this component. The complete modifier chain stays on the actual component; the wrapper delegates parent data and owns the sibling key. Keep sources and dedicated editing states outside observed callbacks. Evaluation and input failures follow ordinary runtime cleanup.

Emits one externally controlled tab.
The component renders indicator only while selected is true and emits matching tab semantics. It installs neither focus nor activation; compose onActivate with the same enabled state for a shared primary-pointer and focused Enter-or-Space action, while pointer-specific actions remain ordinary modifier behavior.
Receiver
active owner-thread screen scope.
Parameters
unresolved tab label.
externally owned selected state.
requested logical width.
whether enabled appearance, hover, and semantics are used.
selected-state presentation.
active behavior including caller-owned focus, activation, and pointer actions.
optional stable sibling identity.
Throws
when a custom indicator does not emit exactly one root.
when no runtime screen evaluation is active.
Literal overload of Tab with the same ownership, failure, and no-implicit-focus-or-activation contract.
