Create a browser (Beta)
Beta: create a browser sandbox, which runs one persistent Chrome that other sandboxes attach to. Logins made in it persist across restarts. It keeps its memory when it stops and is never deleted automatically.

Body
HiDPI renders pages at twice the resolution, so the live view is sharp on HiDPI screens, at four times the pixels for the browser to render and stream. Off by default, and fixed once the browser is created.
IdleTTLSeconds stops the browser after this long without use. A stopped browser resumes with its memory on the next connection. Defaults to the sandbox default; 0 disables the idle stop.
x >= 0Name of the browser sandbox. Generated when omitted, as "browser-" followed by the browser's ID.
VCPUs and MemBytes size the browser sandbox, as for any sandbox. With neither set, a browser gets 2 vCPUs and 8 GiB.
