/* reskin-practice.css — Practice papers (#surface-exam) header + gap-band styles.
   Scoped entirely under #surface-exam. The single-queue card styles (.pri-list,
   .pri-card, .pri-rank, .pri-foot, .skel-*) were removed in PR2e — the surface is
   now the handoff's 3-group layout (To take / Completed / Needs feedback), whose
   .pe-* chrome lives in appshell.css. What remains here: the editorial header
   (.rk-prac-*) and the amber gap band (dark variant included so both themes stay
   intentional). Tokens come from themes.css where they exist. */
