"""Behavioral coverage for the modular Settings shell.

The leaf harness provides focused assertions around the extracted navigation
and lifecycle primitives. The coordinator smoke separately loads the real
settings.js module through Node's native ESM linker together with the real
Settings shell modules, covering their import/export contract and the public
open/close wiring.
