- Fix JsonDataNode::getChildReadOnly() to handle JSON array access by numeric index - Fix test_ui_showcase to use JSON array for children (matching test_single_button pattern) - Add visual test files: test_single_button, test_ui_showcase, test_sprite_debug - Clean up debug logging from SpritePass, SceneCollector, UIButton, BgfxDevice The root cause was that UITree couldn't access array children in JSON layouts. UIButton hover/click now works correctly in both test files. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
