# Original skin model and version scope

Java 1.21.11 classic player: head8×8×8, body8×12×4, limbs4×12×4; slim arms3×12×4. Skin UV dimensions64×64; legacy64×32 has mirrored left limbs and no new lower-half overlays. Outer head expands0.5 model units, other outer layers0.25. Box UV nets preserve each face's rectangular pixel region. Cape local texture64×32, box10×16×1; no equip/account feature.

Renderer implementation is original Cookie Tools code: posed cuboids, orthographic projection, nearest texture sampling and per-pixel depth-sorted alpha. Lighting is an explicit original preview parameter, not game shader output. No game textures, proprietary rendering code or external renderer assets are distributed. Transparent skin documents remain transparent locally; game clients may enforce opaque base regions.

Avatar samples face X8..15,Y8..15 and optional hat X40..47,Y8..15. Editor exposes UV masks and independent native PNG exports. Resource packs use own metadata75.0 and only user-generated textures. Painting asset IDs/dimensions are normalized numerical facts; totem item texture reference is verified against the official client descriptor without copying its file.

Public API endpoints/hosts are verified through official authlib 7.0.61 constants and actual request tests. Profile lookup and texture fetching use allowlisted HTTPS, public-address DNS checks, pinned TLS, bounded responses/caches and rate limits. No arbitrary URL proxy, credentials, server inventory or private profile integration.
