// Validation ordre des sections — fiche Lou-Ka (ordre DOM = ordre visuel)
// Refonte 2026-09-04 : sections `.lk-*` / ids ; vérifie sur mobile que
// l'ordre visuel est croissant, que la page s'ouvre en haut (scrollY 0), que
// le héro (prix + galerie) est le premier contenu, qu'aucune section ne porte
// un `order` CSS et qu'il n'y a pas de débordement horizontal.
// Usage : node frontend/scripts/check-order.mjs [uid] [baseUrl]
