v0.3.0

Opt-in mobile content for the recovered-source port:

• Seven track colours and random fringe colours.
• Mobile path pieces and trampoline bounce rings.
• The ten-level Pro-Challenge campaign, with separate progress and high scores.

Enable Mobile extras in the port options to access this content. The original Windows behaviour remains the default, verified by the replay and session oracles.

The attached snail-port-assets-v1.tar.gz contains the original PC asset archive and converted mobile overlay for deployment builds. Its size and SHA-256, plus the identities of both archives, are pinned in port/deploy-assets.json on master. The attachment does not include executable game code.
