/* Jovaii Swiss Style 1.0.0 — the base stylesheet for Jovaii web pages (jovaii.com, Proposal Hub).
   International Typographic Style: paper, black, grey and one red; sans-serif grotesk; flush left,
   ragged right on one red axis; visible grid; objective black-and-white photography with credits.
   No rounded corners, no shadows, no gradients, no decoration.
   Canonical URL: https://jovaii.com/assets/swiss/1.0.0/swiss.css (immutable; a change ships as a new
