   LOGO THEME — paints the site in the Ecosabor mark's own colors.
   Leaf green is the primary brand accent (locked via data-force-accent="leaf"
   in main.js), the logo orange becomes the warm secondary (replacing the old
   gold AND the export-blue data layer, since the mark has no blue), and the
   primary CTA carries the logo's green→orange arc as a living gradient.
   Loaded LAST so it owns the brand tokens and the primary button.
