Add a new characterHeightScaler runtime component and characterHeightScalerEditor for Unity to auto-detect and apply a model scale to match the GKC standard height (capture/apply/reset, foot alignment, debug UI). Update DudeAvatar materials to assign main textures, clear legacy shader keywords and enable XR motion vectors. Modify launchObject material to use transparent surface settings, correct render queue/blend/ZWrite and disabled shadow/depth passes for proper particle rendering. Update ParticlesLight prefab to include UniversalAdditionalLightData and URP-related light fields (cookie size, shadow & rendering layers, etc.). Add new Flaco alien folder with prefabs/meshes and new house materials; remove some legacy alien FBX files. Also include Scene and ProjectSettings updates to accommodate the changes.
Convert MainMenu and LoadingScreen UXML/USS to responsive layouts (percent-based sizing, media queries for wide/tall screens), adjust spacing, fonts and colors, and refine spaceship icon and button styles. Update MainMenu and LoadingScreen controllers to force the root TemplateContainer to occupy the full screen. Add Assets/Resources.meta. Update metadata and LFS object IDs for several Unity assets (ReflectionProbe-0.exr.meta importer fields and AssetOrigin, Komikax font LFS oid, Loading.unity, DefaultVolumeProfile.asset, and project settings hashes) to reflect import/serialization changes.
Add a full Unity project scaffold: Input System actions (.inputactions + meta), SampleScene and scene meta, URP render pipeline and profile assets, TutorialInfo (scripts/icons), a Readme LFS pointer, ProjectSettings (audio, graphics, input, quality, XR, etc.), and Packages/manifest.json. Sets up default player and UI input mappings, rendering settings, and editor/project configuration for the project.
