/* ============================================================
   QUESTION CONSOLE  (core/question-console.js)

   Lutfi's "Quantum Dawn Question Console" design, as a look for the
   question sheets. The design's sizes are kept for a laptop; a short
   laptop screen (720 px) gets tighter spacing, a phone held upright the
   design's own narrow layout, and a phone held sideways a compact card
   with no stage rail (its facts move into the header).

   Every rule starts .sheet-console .qc: the console's parts still carry
   the plain sheet's class names (sheetOption, sheetAction, sheetMeter...)
   as hooks, and this keeps the plain sheet's styling for them out.
