v1.0.0-beta

First playable release. An ancient entity corrupts your world through invisible doors leading
into a procedurally-generated Infinite Corridor dimension.

• Invisible doors, fully-connected room-by-room corridor generation (cobblestone halls, birch
  forest, distorted structures)
• Unseen-presence dread system (no rendered monster, no jumpscares)
• Lore books, corruption evolution, and a ritual win condition at the Source Room

Requires Minecraft 26.2, Fabric Loader >=0.18.4, Fabric API, Java 25.

Beta: the mod's block/item/effect ship with placeholder textures for now — everything else
uses vanilla assets. Balance and pacing are untested against real playtesting.
