Add OTB talking bear sprite pack and runtime assets

[leonnpowell-del]

Summary

This adds the OTB brand-facing art pipeline needed to generate and run a talking human-bear hybrid sprite set. The goal is to provide production-ready 2000x2000 layered assets, plus a runtime-friendly frame/spritesheet manifest for real-time speech-driven playback.

What changed

• Updated src/config.js for the 10,000-edition workflow:
  • namePrefix, description, and baseUri placeholder updated
  • output format set to 2000x2000 with smoothing: false
  • layer order changed to Background, Body, Clothing, Eyes, Mouth, Headwear, Accessories
  • shuffleLayerConfigurations enabled
  • disabled generated background to rely on layered PNG traits
• Added rendered logo assets:
  • official-logo-2000.png
  • layers/Accessories/Logo#1.png
• Added full OTB talking-bear sprite pack under sprites/otb_talking_bear/:
  • base, mouth (6 viseme frames), eyes, brows, nose, hair FX, and preview frames
• Added runtime builder:
  • utils/build_otb_sprite_runtime.py
  • package.json script: npm run otb_sprite_runtime
• Generated runtime outputs:
  • per-frame talk/idle composites
  • talk_spritesheet.png and idle_spritesheet.png
  • runtime/manifest.json with viseme map, state timing, and runtime hints

Notes

• The runtime builder is implemented in Python/Pillow so it works in environments where native Node canvas binaries are unavailable.
• Manifest timing hints currently target faceSolveFps: 60, visemeUpdateHz: 24, and audioSmoothingMs: 80.

Pull request overview

Adds an OTB “talking bear” sprite/runtime pipeline: new 2000×2000 layer configuration for edition generation, plus a Python (Pillow) runtime builder that composites frames, builds spritesheets, and emits a playback manifest under sprites/otb_talking_bear/runtime/.

Changes:

• Added utils/build_otb_sprite_runtime.py to generate per-frame composites, spritesheets, and a runtime manifest.json.
• Updated src/config.js to a 10,000-edition, 2000×2000, non-smoothed output workflow with a new layer order and shuffled layer configurations.
• Added an otb_sprite_runtime npm script and committed generated runtime outputs (sprites/otb_talking_bear/runtime/manifest.json).

• Same file-handle issue as in composite_frame: with Image.open(frame_path).convert("RGBA") as frame: puts the context manager on the converted image and can leave the original file-backed image open. Use with Image.open(frame_path) as img: and convert inside.
