ADDED Requirements

Requirement: The app SHALL ship curated additional puzzle packs

The app SHALL ship additional curated packs alongside the existing three-level MIAU teaching campaign. Each added pack SHALL contain valid levels with stable pack and level ids, dimensions, entities, and title or hint metadata; adding these packs SHALL not change the teaching campaign's identities or order.

Scenario: Additional curated content is available

• WHEN the player opens the pack and level selector
• THEN the selector lists the built-in teaching pack and every other valid bundled pack with stable ids

Scenario: Imported content does not replace built-ins

• WHEN a valid local or shared pack is loaded
• THEN the three MIAU teaching levels and other valid bundled packs remain selectable
