   atlas-edn · MODE LUDIQUE (POC item 63)
   -------------------------------------------------------------
   CSS dédié au "testing effect" — masquage par flou des éléments
   marqués `.ludic-hide`, révélation au tap/click, popup d'auto-
   évaluation, heatmap récap, toggle global.

   Convention : tout est inerte par défaut (pas de body.ludic-on),
   donc l'inclusion de ce fichier ne change RIEN tant que le mode
   est OFF.
