head

Wraps a block to preserve dynamic variables across async boundaries. Captures
C<$*UI-APP>, C<$*UI-PARENT>, and C<$*UI-ID> from the call site and restores
them when the returned closure is invoked. Also sets up a fresh C<@*UI-NODES>
for the callback.


Returns the underlying widget object. If C<$widget> has an C<.obj> method
(builder pattern), calls it. Otherwise returns C<$widget> directly.


Method trait that prevents duplicate event handler registration. Wraps the
method to call C<$.should-add> with the method name, returning early if the
handler was already registered for the current C<$*UI-ID> context.
