Every mock consumer is now gated on the demo flag inline (canonical Vite DCE
idiom — the cross-module DEMO_CONTENT_ENABLED const defeated folding). But
the real leak was films.ts's module-level allGenres/allSources exports:
[...new Set(mockFilms.flatMap(...))] is unprovably pure, so the treeshaker
kept the whole module — array, plex:// and cloud.example.com hosts and all —
even with zero live references. The mocks directory is now declared
side-effect-free in vite.config (they are pure data by design), so unneeded
mock modules actually drop.
Verified: clean dist build → entry bundle AND dist-wide grep show zero
mock hosts (spotify/track/example, cloud.example.com, plex://, tmdb image
host). Demo/dev builds (VITE_DEMO_CONTENT=true or import.meta.env.DEV) keep
the full pack. Tests: 353/356, failures are the three documented
pre-existing ones.
