Fix the pause: it would not hide, it was off centre, and it was too small

Three faults in 1.0.4, and the first was the serious one.

  1. It never went away. Core hides the overlay with `#pause { display: none }`
     and shows it with `#pause.paused { display: flex }`. 1.0.4 styled the BARE
     #pause with display:flex, which wins on specificity, so unpausing removed
     the class and changed nothing — GAME PAUSED sat over the table for the rest
     of the session. Every rule here is now scoped to `.paused` and `display` is
     not set anywhere.

  2. It was off centre because I repositioned it. Core already centres it: a
     full-width band at top calc(50vh - 100px), column flex, centred both ways,
     pointer-events none. That layout was correct and 1.0.4 fought it with
     left/bottom/transform. It is left alone now; only the height changes, and
     the top moves up by exactly half the extra so the centring holds.

  3. It was small: a 322x116 panel in the corner. It is now core's full-width
     band at 300px with a 170px dial — against core's own 100px — and the
     caption at 24px to match core's.

Guarded: check-behaviour now parses the stylesheet and fails any rule that sets
display on an unscoped #pause. Verified it bites. It strips CSS comments first,
because the first version of the guard reported the comment explaining the
guard — which is exactly what the template guard did last time, so that is twice
now and the lesson is written down properly.

Verified by driving the real toggle: running → display none, box 0x0, no class;
paused → display flex, 341x302, centre X exactly on the viewport centre;
unpaused again → display none, box 0x0.

Version 1.0.5.
