"""GX Hub Studio packager — build the submission zip in the hub's expected shape.

Runs the Studio validator first and REFUSES to package if validation fails.
The zip puts the game folder's contents at the zip root (index.html at the
top, which is what the hub's checkEntries wants), and enforces the hub's
25 MB zip cap (LIMITS.maxZipBytes).

Usage: python3 package.py <game-folder> [-o out.zip] [--title T] [--description D]
