/* ===========================================================================
   Quiz — the evaluation layer of Music Lab (/quiz).
   Built on the Music Lab tokens (music-lab.css) and the Practice Lab pieces
   (practice-lab.css: segmented controls, inputs, the fretboard;
   practice-chords.css: the keyboard). Like the labs, nothing here defines a
   colour of its own: it composes tokens, so day and night both work.
   Mobile first; the question screen is touch-first (targets ≥ 48px).
