v1.0.0-mc26.51

Added

• First public Windows x64 client release for Minecraft Bedrock 1.26.51.01 and LeviLamina 26.51.*.
• A 3D cave background with baked colored lighting, animated flowing lava, wall-mounted soul torches, and flame/smoke particles.
• A loading-image-to-cave intro synchronized with the Minecraft title animation and menu fade, with Esc to skip.
• Camera views and transitions for the main menu, world list, settings, dressing room, Realms, and Marketplace.
• Resource preloading, reusable scene buffers, and bounded animation steps after rendering stalls.
• A lip v3 client package manifest, English/Chinese READMEs, and agent maintenance instructions.

Fixed

• Straight and curved rail texture orientation and connection boundaries.
• Menu title placement below foreground controls, and camera return during UI exit transitions.

Changed

• Release packages include runtime files and basic documentation only.
• Versions use the Playback-style -mc26.51 compatibility suffix; the feature version is 1.0.0.

Removed

• Unused rendering prototypes, historical backups, unused Mojang/STUDIOS animation and startup audio assets.
• Automatic texture-preload, camera-state, frame-gap, and periodic performance logs, including their diagnostic-only timers and counters.

See README.md for outstanding rendering details and validation limits. Native UI stalls are not claimed to be fixed.
