// TestIssue218_LocalInternetRadioPresetSurvivesSync drives a syncPresets
// against a fakespeaker that emits the exact LOCAL_INTERNET_RADIO preset
// XML pasted by the reporter in issue #218:
//
//	https://github.com/gesellix/Bose-SoundTouch/issues/218
//
// The preset's contentItem location points at
// `https://content.api.bose.io/core02/svc-bmx-adapter-orion/prod/orion/station?data=...`
// — a Bose cloud URL that broke when the cloud shut down. After
// migration AfterTouch must keep that URL reachable (via the DNS
// interception hook + serving the /core02/svc-bmx-adapter-orion path
// itself); the first step is verifying the URL is preserved verbatim
// through the device → datastore sync round-trip rather than getting
// rewritten or dropped.
//
// This test locks in the "location preserved verbatim" contract. When
// AfterTouch starts rewriting the URL to its own base (the eventual
// fix for #218 — see also issue #195's AUX divergence and #234's
// factory-reset preset revert which overlap with the same DNS/HTTPS
// interception story), this test will need to flip its assertion
// accordingly. The fixture stays — the assertion records the
// decision.
//
// Pattern reference: pkg/service/marge/recents_sourceproviderid_regression_test.go
// is the existing "regression test = locked-in behaviour" exemplar in
// this codebase; this is the first one to drive the fake speaker via
// fakespeaker.Config.FixtureOverrides rather than an inline
// httptest.NewServer.
