Import a Suno LP prompt file

The Import button also accepts a .suno file - a Suno "LP" prompt file that holds a whole set of tracks. Importing one creates a project named after the LP and turns each track into its own Song card, carrying that track's title, description, style, lyrics, language, and date - the entire set brought in at once, instead of pasting each song by hand.

It's the quickest way to seed a new project from a batch of prepared song prompts; a plain .json still imports exactly as before. One rule: because Songs can't live in the Global environment, import a .suno into a normal environment.
