/* =========================================================================
   FULL LENGTH TEST — AKSH NITI PREMIUM CONSOLE

   The second interface a candidate can choose, opposite the Eduquity replica.
   Its own design, not the study app's exam console borrowed: that one is built
   for a 25-question daily set on a desktop, and a 200-question sectional paper
   sat on a phone is a different problem.

   ── What it is designed around ────────────────────────────────────────────

   One thing is read for an hour, so the question is the only warm surface on
   the screen and everything else is cool chrome around it. Reading happens on
   paper-white; controls live on slate. That split is the whole idea.

   The thumb owns the bottom of a phone. Save & Next is pressed a hundred times
   in an hour, so on a phone it sits in a fixed bar at the bottom rather than
   after the options where it would be a scroll away. On a laptop the same
   controls sit inline, because there the mouse is already there.

   The palette is a rail when there is room and a sheet when there is not. It
   is never a thing to scroll past to reach the question.

   ── Tokens ────────────────────────────────────────────────────────────────
   Deliberately its own set (--px-*), not the study console's --tm-*. The two
   consoles are meant to look like different products, and sharing a palette is
   how that stops being true.
