/* SwarmCeptor: simple company page, 2026-11-04.
   Colour tokens between the TOKENS markers come from the chosen variant
   (A: Tactical Green approx. #4a5a46; B: Nardo Grey approx. #686a6c; no official hex exists).
   Dark by default, light under prefers-color-scheme: light. The hero keeps the variant colour in both.
   No web fonts (system sans), no scripts, no inline styles: the CSP allows styles from this origin only.
   EU marks are always full colour on a white panel (FE handbook ch. 11.1: no achromatic marks on websites). */
