-Account login uses a dismissible dialog before the model onboarding credential editor. The dialog uses a compact, right-aligned action row with the primary action last. The sidebar displays the profile name, falling back to the server-masked phone number or email when the name is absent; it stays blank while the profile is loading. Dialog copy and the sidebar account label are not text-selectable; the copy-link button remains available. Waiting shows a copyable authorization link and a loading indicator; timeout and failure require an explicit retry. Closing a waiting dialog cancels its Host attempt. The sidebar can reopen the same API-key editor through the settings coordinator. Browser login preopens a tab on the click and navigates it only when that attempt receives its authorization URL; blocked popups retain the copy-link route. The original tab retains the authorization window handle and closes it on failure, timeout, or cancellation. Login feedback stays in the original tab; callbacks never navigate to a second Web UI.

Failed current requests retain the latest successful profile for the same credential in Host memory; credential changes and disposal clear it. Exchange registers the submitted device information.
 
 accountRequestHeaders overlays requestHeaders for current, balance and embedded Platform page/API requests. Cookie pairs merge by name so routing overrides retain other deployment cookies. Authorization initialization, exchange, cancellation and logout keep requestHeaders. Both maps remain private to Host and Electron main; renderer bootstrap receives only origin and token.
