MCP guide and guided tour

MCP guide video, post-onboarding tour, uploads hub, and exports grid view.

MCP guide video — open from the MCP page, Help tab, bottom widget, or post-onboarding tour; docks to a corner for picture-in-picture while you work.
Post-onboarding guided tour on desktop after your first chat — golden spotlight walks you through Exports, MCP, and Connections.
Uploads hub at /uploads — browse memory sources and open detail views; legacy /sources URLs redirect.
Exports grid view — switch between list and grid on the exports hub.

Post-onboarding tour adds an MCP watch card, golden nav buttons, and smoother spotlight motion.
MCP page — cleaner subnav, link spacing, and card layout.
Connections — app sources, import logs, and uploads cards with live connection status dots.
