/* UTSL marketing site — shared stylesheet.
   Direction: editorial engineering consultancy. Swiss 12-column grid, hairline
   rules instead of floating cards, serif display + Plex Sans/Mono, ink + one
   petrol accent, 3–4px corners, no gradients/glows. Built for buying
   committees (IT, finance, procurement) who scan for terms, proof and price.
   No build step; every class used across the 14 pages is defined here. */
