/* The website. The product's own tokens (tokens.css) and typeface, used plainly: flat colour, no gradients, no tinted boxes around icons, no pills, no label above every heading.
   One idea runs through it: a receipt. The hero prints one, the ticket is itemised like one, and a strip shows the 30 seconds Vehra keeps rolling until you point.
   Motion is for those, and nothing else. Everything is readable at rest; with reduced motion the finished state is shown and nothing moves. */
