/* TeraThreshold promotional site
   Dark canvas modelled on linear.app's layout language (hairlines, product-as-hero,
   split section heads, mono figure labels); feature rows follow the MIT-licensed
   Tailark "Dusk" pattern. The four pillar colours come from logo.svg.
   Fonts (Google Fonts, loaded in each page): Barlow Semi Condensed for headlines,
   Barlow for copy, JetBrains Mono for figure labels and numbers, and Archivo
   (ExtraBold Italic at 125% width, subset to the letters of "TeraThreshold") for the
   wordmark only: the wide forward lean echoes the chevrons in the mark. */
