/* Xpert WorX — parent brand site.
   Design language follows intelxpert.com and xpertradar.com: near-black ground,
   thin uppercase editorial headings, mono micro-labels, numbered sections.
   The accent is the blue from the Xpert WorX mark; each product card carries
   its own product accent so the family reads as a family. */
