- Add DesktopSandbox class that integrates timer, JSON, crypto, and VirtualFS APIs - Fix mouse coordinate handling: GLFW reports window coordinates, not physical pixels - Fix font path resolution to search multiple locations for test apps - Fix screenshot capture timing (capture before buffer swap) - Fix test app CSS: use border-width instead of border:none, add display:block - Fix test app Lua: add document nil checks, use HTML entities for symbols - Update hot_reload to reset sandbox state on reload Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
