"""SoulSync — VIDEO side API package (isolated).

A SEPARATE Flask blueprint from the music API (api_v1). It reads only
database/video_library.db via VideoDatabase and imports nothing from the music
API or music database layer. Registered in web_server.py with a single additive
line at url_prefix '/api/video', so music routing is untouched.
