/* What both pages share.
 *
 * The VM page and the agent page had two copies of the same tokens, the same
 * body rule and the same control styling, which stayed in sync by hand until
 * the agent page grew a terminal of its own and the copy that mattered lived
 * only in the other file. Everything here is used by both; anything used by one
 * stays inline in that page's <style>. */

   hidden the moment the download ended, stayed on screen sitting at 100%, and
