Theatre Addon

• Server-only NeoForge mod (1.21.1) for staging utilities; no custom registries so vanilla clients can join.
• Commands (operator-only):
  • /theatreaddon light add <name> <x y z> [level], /theatreaddon light toggle <name> on|off|flip, /theatreaddon light clear <name>, /theatreaddon light list.
  • /theatreaddon spotlight add <name> <x y z> [length] [level], plus toggle/clear/list like lights; creates vertical light beams using vanilla light blocks.
  • /theatreaddon curtain define <name> <from> <to> [block], /theatreaddon curtain toggle <name> open|close|flip, /theatreaddon curtain remove <name>, /theatreaddon curtain list; curtain fill capped at ~80k blocks.
  • /theatreaddon costume give <preset> [player] with presets ringmaster, performer, clown, phantom (dyed leather outfits + baton); /theatreaddon costume list.
  • /theatreaddon decor kit <type> [player] for theatre, circus, or lighting prop bundles; /theatreaddon decor list.
• Light and spotlight fixtures store the original block state and swap to vanilla light blocks when on; names are case-insensitive and saved per world.
• Curtains restore to air when opened and fill with the chosen block when closed; intended for empty curtain bays.
• Everything runs on the dedicated server (mod id theatreaddon), no assets or client hooks required.

Known limitations / future ideas:

• Curtains overwrite anything in their volume; avoid defining over builds you want to keep.
• Light fixtures and beams expect chunks to be loaded when toggled; large or distant rigs may need chunk loaders.
• Decoration kits and costumes are simple presets; add more variants if you want themed shows.
