/* ============================================================================
   grader-pane-qset.css — the question-set pane. Step 5, pane 1 of 7.
   Tokens only; tools/grader-tokens-only.js guards this file.

   THIS PANE USES THE READING SURFACE, NOT THE STAGE.
   The image pane's stage is a VIEWING surface — true neutral, sized so a
   photograph is judged honestly. A question set is text, so the centre column
   becomes the READING surface the design specifies in §5b of
   "Unified Grader v5 panes.dc.html": #131416, measure capped, column centred
   rather than stretched. Neither surface borrows the other's treatment.

   ⚠ #131416 and #17181b are DESIGN-STATED but NOT IN TOKENS.css — they are
   labelled in the design's own §5b swatch ("#131416 · 68CH") and declared in
   that file's :root as --read / --read-col. They are recorded in the harness's
   SPEC_LITERALS, not invented here. If TOKENS.css ever names them, switch.
