   Timer group centred in the bar; Skip pinned right, mirroring Resume on the

   group centred against Skip's width rather than the screen's.

   Do NOT restate `position` here. This block once carried `position: relative`
   to give `.rt-skip` a containing block; `position: fixed` above already is
   one, and at equal specificity the later rule won — which dropped the whole
   bar out of the viewport into normal flow at the bottom of <body>, hidden
   behind the overlay. The timer kept running and dinging invisibly, so it read
