What makes the web version special

• Mobile-first PWA - optimized chat controls, keyboard-safe layouts, drag-to-reorder projects
• Background notifications - know when your agent finishes, even from another tab
• Self-update - update and restart from the UI, server settings stay intact
• Cross-tab tracking - session activity stays in sync across browser tabs

Plus everything from the shared OpenChamber UI: branchable timeline, Git sidebar, terminal, voice mode, and more.
