/* ==========================================================================
   CLIMATE-HEATMAP — visualisation climatologique de France.
   Refonte v2 : table aérée, cellules carrées plus larges, première colonne
   stable mais sans sticky overlay (qui causait du chevauchement). Pure CSS,
   table HTML sémantique (SEO-friendly), responsive avec scroll horizontal
   et indicateur de défilement.
