- Fix texture state management in BgfxDevice: defer setTexture until submit() - Add transient instance buffer support for multi-batch rendering - Add ParticlePass with fire, smoke and sparkle particle systems - Load multiple textures from config (texture1..texture10) - Visual test now demonstrates multi-texture sprites and multi-particle effects 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
