/* Axiolith marketing site. Dark charcoal, one teal accent used sparingly, the Strata layers as the only motif.
   Plain on purpose (2 Oct 2026): flat surfaces, no glows or gradients, no motion, sentence-case labels, small radii.
   Fonts come from the shared tokens.css; colours are the site's own (the site is dark only). */
