/* ============================================================
   UK-GAMERS — United Kingdom template
   Design: "DARK DATA TERMINAL" — flat, matte navy, ZERO glow.
   Distinct from every network site: no box-shadow, 1px silver
   hairlines, radius 0–2px, mono figures (tabular-nums), a dense
   ranked comparison module first (not a newspaper, not cards-hero).
   Palette (3 core + neutrals): navy bg / navy surfaces / silver ink
   + muted slate + crimson accent + silver hairline.
   Fonts: IBM Plex Sans (UI/headings) · IBM Plex Mono (odds/numbers).
   NOTE: fonts linked from Google for the template preview;
   self-host (woff2) at deploy per master.md fonts_self_hosted rule.
