GAVTI LUCKY 5 ONEBLOCK v1.3

12 waves x 550 breaks (6,600 progression breaks).
Exactly 1 Structure Lucky Crate per 550-block wave.
Generator at 0,1,0 and permanent Barrier at 0,0,0.
Zero-air-gap regeneration: the old Lucky Crate is directly replaced by the next one.

BALANCE UPDATE v1.3
- All five Lucky Crates are now full normal-block height.
- Grass blocks are available from the early game.
- Waves 2-6 give noticeably more ore blocks for natural progression.
- Waves 2-3 can give farm animal spawn eggs (chicken, sheep, pig, cow) plus some utility mobs.
- Later waves add more mob spawn eggs, obsidian, Nether and End resources.
- End Portal Frames are very rare late-game rewards (Wave 10+).
- Green/Red no longer mean constant armor/tools: enchanted gear chances are very low.
- Every Lucky Crate still gives only one reward type at a time.
