Phase 7 - Text Rendering: - Add BitmapFont with embedded 8x8 CP437 font (ASCII 32-126) - Add TextPass for instanced glyph rendering - Fix SceneCollector::parseText() to copy strings to FrameAllocator Phase 8A - Multi-texture Support: - Add numeric texture ID system in ResourceCache - SpritePass sorts by textureId and batches per texture - Flush batch on texture change for efficient rendering Phase 8B - Tilemap Rendering: - Add TilemapPass for grid-based tile rendering - Support tileData as comma-separated string - Tiles rendered as instanced quads Window Resize: - Handle window resize via process() input - Call bgfx::reset() on size change 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
