/* ============================================================================
   style.css — the page around the console

   Almost nothing lives here. The interface itself is painted into one canvas,
   so CSS only has to do three jobs: black out the page, fit the 1024x768
   console into whatever window it has been given without blurring it, and
   dress the boot gate.

   [hidden] is forced first, because an author `display` on an element beats
   the user-agent stylesheet's `[hidden] { display: none }` regardless of
   specificity — which means setting el.hidden = true silently does nothing and
   the element stays on screen while every probe reports it as hidden. That has
   cost real time on two previous projects; it is not going to cost any here.
