/* The sales website's only stylesheet.

   Direction: the job docket. Navy and blue (the OntraOS app theme; orange stays in the logo only) and a
   condensed DIN-style face (Bahnschrift on Windows, DIN on Apple, Roboto
   Condensed or Arial Narrow elsewhere). No web fonts: every face is a
   system font, so the site loads nothing from other websites.

   Light and dark follow the device (prefers-color-scheme). Text colours
   pass WCAG 2.2 AA on their backgrounds in both themes. */
