About

Replaces vanilla elytra with a 3-tier progression system: Copper Elytra (craftable from copper + phantom membrane + lightning rod, found in End Ships, no fireworks), Supersonic Elytra (copper + iron, boost engine via * key, overheats after ~2.5s), and Reinforced Supersonic Elytra (supersonic + diamonds, 50,000 durability, no overheat, 30% stronger boost). Vanilla elytra are purged from loot tables, player inventories, and item frames. Uses Cardinal Components for per-player overheat tracking.
