/* ============================================================
   NBME EXAM FORMAT — html[data-exam-format="nbme"]

   Matches the LIVE NBME test-delivery software (Chris's screenshot of
   starttest.com): left "Question Status" rail listing every item, a
   boxed "Item: 32 of 50 / Block: 3 of 5" top-left, Previous · 32/50 ·
   Next centred, tool icons top-right, options in a bordered box with
   "A." letters and an "ab" strike glyph, blue "Proceed to Next Item",
   navy timer box bottom-left, Pause centre, End Block right.

   Pure CSS over the existing markup — engine, grading, stats and
   shortcuts are unchanged. Only the assessment overlay is affected.
