- docker-compose: roundcube service with inline config (Gmail/iCloud/Yahoo presets, framing allowed, persistent key); only reachable through the hub
- hub passes /webmail/ through to Roundcube behind the passkey sign-in; Microsoft's sign-in page opens in the whole window and returns to the Mail tab
- M365_* settings add 'Login with Microsoft 365' (README has the Entra app registration steps)
- Side menu collapses to icons or hides completely (remembered per device, Ctrl/Cmd+B)
- tools/webmail-test.js
