`assets/resources`

Runtime-loadable resource bundle. Cocos Creator treats everything under resources/ as eligible for resources.load()/loadBundle() APIs.

resources/
├── prefabs/      # reusable prefabs (player, enemies, bullets, particles)
├── textures/     # atlas textures, sprite sheets (forest/castle/mocastle)
├── audio/        # bgm (mp3) and sfx (wav) — total ≤ 500KB (req 16.5)
└── configs/      # JSON config tables (enemies, levels, items, story)

First-package footprint must stay ≤ 4MB (req 18.7). Non-chapter-1 resources are expected to sit under assets/resources/chapter2/, chapter3/ etc. as remote sub-packages once those chapters are implemented (out of MVP).
