- Create DebugOverlay class using bgfx debug text API - Display FPS (color-coded: green >55, yellow >30, red <30) - Show frame time, sprite count, draw calls - Show GPU/CPU timing and texture stats from bgfx - Add "debugOverlay" config option to enable at startup - Smooth FPS display over 250ms intervals 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
