+Open Escape/Start, then Character customiser in the complete Windows package.
+First-run setup now prepares the clothing/body library, presets, tattoos, all
+owned pro/special characters and their authored lighting. These preparation
+steps previously ran only in private feature-test folders.

+Character additions have their own release fingerprint. Updating an already
+prepared copy can build these assets from its original Xbox source without
+reconverting maps. Setup publishes a new character generation only after the
+library, lighting and native roster all succeed. Existing imported models and
+saved profiles are preserved; interrupted preparation can reuse its own cache.
+Players do not need Python, Blender or development tools.

+The runtime retains the visible skater if a library is missing or incomplete.
+Returning from a native/imported character reapplies the saved outfit and binds
+its visible rigs again. Native models use their own shader parameter rows and
+specular textures, including torso slots absent from the default stock model.
+Customiser pieces retain tattoo/hair composition and use character SH/key/rim
+lighting on retail maps. Custom maps continue to use their ordinary PBR lights.
