    /// Those menus were written when the whole game lived in a single scene. They find
    /// or create the dialogue system, the UI canvases, the player and the camera rig,
    /// and save the result into one scene. After the split into Bootstrap / Systems /
    /// Level, that assumption is false, and running them does damage rather than work:
    ///
    ///   - Pointed at a level, they rebuild systems content that already exists in
    ///     Systems.unity, leaving duplicate UIStateControllers and dialogue runners.
    ///   - Pointed at Systems, PlayerControlSetup drags navigation in with it. The
    ///     baked NavMeshData is embedded rather than an asset, and NavMeshData prefers
    ///     binary serialization, so the whole scene silently turns binary — the exact
    ///     problem that took a bisection to find the first time (CLAUDE.md trap 1).
    ///
    /// Both were observed, not theorised. So the builders are blocked rather than
    /// retargeted, and deliberately not deleted: UILayerSetup alone is 818 lines that
    /// still record how the UI layer is wired, and that record is worth keeping until
    /// the prefabs replace it (docs/restructure-plan.md Phase 5).
    ///
    /// Asset generators are unaffected. Regenerating SkillDefinitions or the candidate
    /// registry from JSON touches no scene and stays available.
