/* =========================================================
   ТК БЕТОН — design tokens
   Palette grounded in the material itself: raw concrete grey,
   rebar-dark ink, and safety-equipment orange (gloves, hazard
   markings on the plant). Data (grades, W/F indices, prices)
   is set in a mono face, like the batch tickets ("паспорт
   бетона") the company issues with every load — that document
   is the design's signature motif.
