   Kalso — kalso.co.uk
   Bespoke jewellery and crafts, handmade in South Wales.

   A static page. No build step, no dependencies, no CDN — the two fonts are
   self-hosted in /fonts, so nothing here phones home.

   The palette and the geometry are both lifted straight from the logo: three
   equilateral triangles in rose, sage and cream. Those same three triangles
   are used through the page to stand for the three things Kalso makes.
