- Fixed: brands with special letters now match their plain spellings. Letters like ß and ø were dropped instead of folded, so Weißer Riese and Røde never matched. Hahnemühle is added to the known list, and amazon.de product pages now read the "Marke:" and "Besuche den ...-Store" bylines. - Fixed: product-line titles with no brand byline, like "WILD JO: 36 Cups ...", now resolve to their known parent brand instead of scoring as suspect. - Fixed: "Keep shopping for" pages on desktop now read the brand row. Every tile there read as "No brand", so the first word of the title was scored as a suspect brand.
