/* ==========================================================================
   Multilingual news website — public stylesheet.

   A mobile-first, typography-forward, editorial design inspired by babel.ua:
   near-black text on an off-white page, a single restrained red accent, and
   generous whitespace. UI text uses Inter; long-form article bodies use a
   readable serif (Source Serif 4). Both are free (SIL OFL) and loaded from
   Google Fonts in the layout <head>.

   No JavaScript is required — this is a progressive, CSS-only presentation
   layer over server-rendered HTML.
