/* uk/style.css — standalone stylesheet for the server-rendered Ukrainian
   landing page (/uk/, issue #223). Deliberately independent of app.css: this
   page ships no JS (CSP script-src 'self' with nothing to load, and no
   client-side theme switching), so it duplicates the small subset of design
   tokens it needs rather than depending on the SPA's stylesheet. Colors/
   fonts are kept in sync with app.css by hand. */
