/* SharpOCR components — CSS translation of the design system's React primitives
   (components/{core,forms,feedback,data}/*.jsx) and ui_kits/site/*.jsx.

   The upstream kit is React with inline styles. This site is static HTML served
   by Caddy from /srv/site, so the same rules live here as classes. Values are
   copied from the JSX, not re-invented: if a number here disagrees with the
   design project, the design project wins and this file is wrong.

   Responsive rules at the bottom are additions — the kit is authored at one
   desktop width and defines no breakpoints. */
