Michael Czechowski	c560676544	feat: implement #4 — replace answer-revealing validation messages with pedagogical hints ... Rewrite ~120 validation error messages across 17 English lesson modules and their localized variants (ar, de, es, pl, uk) to use concept questions, property hints, and directional nudges instead of revealing the exact CSS property-value answers. Priority modules (flexbox, box-model, colors, positioning) fully rewritten. All remaining CSS modules updated. Only message strings changed — no validation logic modifications.	2026-03-28 19:40:28 +01:00
