// Pure unit tests for integrations/paloalto/urls.js — no HTTP, no
// mocks. The builders here feed deep-link markdown into user-facing
// output, so any silent format change would show up as broken links
// in production. The tests spell out both the exact URL shape and
// the boundary conditions (null ids, base-URL env override).
