Role in VulpineOS

In VulpineOS, foxbridge runs as an embedded CDP server — not a separate process. It wraps the kernel’s Juggler client directly:

• One Vulpine browser process shared between TUI, MCP tools, and compatible CDP clients
• Shared browser contexts — fingerprints and cookies persist across all interfaces
• Zero overhead — no second Firefox instance

Kernel → Vulpine browser (single process) → Juggler pipe → juggler.Client
