/* Tysenco web — built on the Tysenco design system (tokens.json).
   Layout concept: a calm technical datasheet — label column + content, hairline rules,
   teal-deep table heads, square corners, technical line drawings instead of stock imagery.
   Light theme only: the public site keeps one clinical, clean look on every device. */
