"""Full public-playlist fetch via the optional SpotipyFree library.
|
|
|
|
The library is GPL-3.0 and user-installed, so it's never imported in tests —
|
|
a fake spotipy-compatible client is injected to exercise normalisation +
|
|
pagination, and the embed fallback orchestration is tested separately. So a
|
|
missing/broken library can never make the link path worse than the embed ≤100.
