// The war room is state, like the board — an open tab should stay honest without

//   1. The countdown, which ticks locally every second off the pushed ends_at.
//      No network for that; the deadline is fixed the moment the Siege spawns.
//   2. The pool, re-polled every 15s. The bar's width is set here and CSS does
//      the animating (a width transition), so a poll that lands a lower pool
//      *slides* rather than snapping. That slide is the whole reason this page
//      exists: it is what turns a number into the town chipping something down.
