3/// A handle that tracks whether a wrapped subtree has
4/// thrown.
5///
6/// The boundary's phase is exposed via `phase()` as a
7/// `Signal<ErrorBoundaryPhase>`. The parent component
8/// reads that signal to decide whether to render the
9/// child or a fallback.
10///
11/// `try_with(closure)` runs the closure and, if it
12/// panics, transitions the boundary to `Caught`. The
13/// closure's return value (if it didn't panic) is
14/// returned to the caller; if it panicked, an `Err`
15/// is returned containing the panic message.
