/* Turnierbericht Sunday Padel – shared design tokens & layout primitives.
   Owned by the lead. Feature agents: read, don't edit. Section styles go into css/<section>.css.

   Design: PadelCompass (same as /blog): near-black page with a fine dot grid, Cyan as primary,
   Yellow as a sparing secondary, white Fraunces headlines, Inter body, JetBrains Mono labels.
   Fonts come from the website's /css/local-fonts.css (Inter 400–900, Fraunces 400–900 + italic 500/700,
   JetBrains Mono 400/500/700), so this file declares no @font-face of its own.

   Everything is scoped under #bericht (the <main> that wraps all sections) so it does not leak into
   the website header/footer; :where() keeps the selector weight of the bare class. */
