/* Varo marketing site — design tokens match the product (varo-portal-vps
   frontend/app/globals.css): warm-white ground, near-black ink, and a
   monochrome accent rather than a brand colour. Instrument Serif for
   headings, Inter for body, same as the product's wordmark and UI.

   LIGHT ONLY, on purpose. There is no prefers-color-scheme block and one
   should not be added back without asking: the owner chose a single
   deliberate look over a theme that follows the visitor's OS. `color-scheme`
   below tells the browser the same thing, so form controls and scrollbars
   stay light for a visitor whose system is set to dark. */

   third-party font request is exactly the kind of thing that can silently
   fail or stall there. Both files are Google's own woff2 (Inter's covers
