Backrooms Builder 0.1.0 - Asset Provenance Notice

Imported architectural models/textures in this project were extracted from the user-supplied SP-Backrooms Revamped 1.20.1 v1.2.0 JAR by SpacePotato / Herr Chaos / contributors and mechanically adapted to the backrooms_builder namespace for Minecraft 1.21.1 NeoForge.

The supplied JAR includes LICENSE_spb-revamped-1.20.1 containing GNU GPL v3 text, while fabric.mod.json declares LGPL-3.0-only. Both facts are preserved here rather than removing attribution. Before public redistribution, verify the upstream project's intended asset licensing and comply with its source/notice obligations.

New Backrooms Builder Java code, recipes, and procedurally generated expansion textures are modifications/new material prepared for this build.
