/* ════════════════════════════════════════════════════════════════════
   DA-52 B · Expertise GPS Ads, décliné du gabarit GEO.
   Aucune particule. UNE idée, LA SOURCE QUI S'ALLUME, transposée à la
   carte : sur un plan dessiné au trait (SVG), un point suit son trajet,
   l'épingle sponsorisée d'un établissement s'allume près de la route,
   puis l'itinéraire y mène et la fiche s'ouvre.
   « GPS Ads » est présenté comme un terme d'usage (annonces Google Maps,
   inventaire Waze), jamais comme un produit Google.
   Rythme : sections nuit et feuilles de papier claires en alternance.
     en-tête (nuit) : titre décalé, photo révélée, preuve externe attribuée ;
     1 le terme (papier) : résumé, scène, quatre formats, frise Waze ;
     2 Del Arte (nuit) : les chiffres publiés par DAC Group ;
     3 ChatGPT Ads (papier) : frise des dates, annonce séparée de la réponse ;
     4 combiner (nuit) : trois moments, trois cartes ;
     5 l'avance (papier) : photo, pratiques ;
     6 méthode + CTA (nuit, une seule bande) ; 7 FAQ + sources (papier).
