/* ============================================================
   ranked-exam.css — Blind exam: Ranked / Practice scoring,
   difficulty, server result card and session summary.
   Markup: js/retinoscopy/app/ranked-view.js
   Loaded just before retinoscopy-theme.css (which stays last); uses its calm palette
   (--ret-ok/with/against/info + ink/tint) and neutrals only.
   Logical properties throughout, so Arabic mirrors for free;
   numbers sit in dir="ltr" islands.
