/* ============================================================
   THEORIST STAGE REVIEW  (core/stage-review.js, window.QStageReview)

   Lutfi's "Quantum Dawn Stage Review" design, carried over value for value
   (the design scoped its rules to .qd-review; here they live under .qsr so
   none of its short class names can reach the rest of the page). Added for
   the game: the dimmed layer it sits on, the student's own choice on every
   card (Lutfi asked for it, 11 Oct), and a compact layout for a phone held
   sideways, which the design did not cover.
