The Side by side page now opens two panes. Each pane shows an organization
dashboard, an agents grid or a project page, chosen from a picker that lists
every organization and project. Pane state lives in the URL and is kept per
viewer. A separator resizes the panes by pointer or arrow keys, closing a
pane goes back to one, and each pane keeps its own focus and scroll through
polling. A pane whose organization's bus is down says so while the other
pane keeps working. On a phone a two-way switch shows one pane at a time.
Panes are read-only. Conversation, room, settings, queue, docs and inbox
pages open in full view; chat.js is a single-instance page with global ids.
