/* Panopticon marketing site — design system
   ------------------------------------------------------------
   Shares its palette, radii and shadow language with the product
   itself (navy / blue / cyan, Inter-style sans, Tabler-derived
   spacing) so the site and the app read as one brand. No webfonts,
   no CDN, no analytics — the site practises what the product preaches.
