- Character models (`public/assets/models/*.glb`: hero, bandit, spearman, shieldman, archer, swordmaster, assassin):
  generated by the project author with [Tripo AI](https://www.tripo3d.ai) (image/text-to-3D, auto-rig and preset
  animations; the skeleton uses Mixamo-style bone names). They are **not** covered by this repository's MIT license;
  their use is governed by the Tripo AI Terms of Service. Please do not extract or redistribute them separately.
- Motion capture `public/assets/anims/mixamo.glb` (attacks, rolls, falls, deaths, get-up, draw/sheathe, the
  enemies' axe / sword-and-shield / longbow / bayonet sets): animations from [Adobe Mixamo](https://www.mixamo.com),
  downloaded by the project author, converted and retargeted by `tools/mixamo`. They are **not** covered by this
  repository's MIT license; their use is governed by Adobe's Mixamo terms. Please do not extract or redistribute them
  separately.
- Chinese jian (straight sword) motion `src/character/mocap/jian-demo.js`: pose keys tracked from a reference video
  of a jian routine by `tools/mocap/retarget.py` and retargeted onto the procedural rig (numeric pose data only; no
  video frames are included).
- Fonts: Ma Shan Zheng, Noto Serif SC, Cormorant Garamond via Google Fonts (SIL Open Font License).
- Poems: 敕勒歌, 李白《侠客行》, 《易水歌》 — classical texts in the public domain.
- Visual reference: "Sakura River Valley" (valley.mengto.here.now) — its rendering techniques (post pipeline,
  lighting model, grass wind, camera rig) were studied and re-implemented from scratch in this codebase; a few small
  standard formulas (e.g. the ACES fit, lamp falloff) match it. No assets from it are used.
- Everything else (terrain, grass, bamboo, the town, sky, weather, townsfolk, procedural animation clips, all music
  and sound effects, voices) is generated procedurally at load — there are no audio files in this repository.
