/* ===========================================================================
   NumFox — "Entra en cada mundo" worlds slider
   ---------------------------------------------------------------------------
   Self-contained and SCOPED under #numfox-worlds so none of these rules can
   leak into (or be overridden by) the host landing page. Generic class names
   like .spot / .car-tab / .wrap only apply inside the section.

   Fonts (Fredoka / Nunito / JetBrains Mono) are already loaded by the consola
   layout, so no extra <link> is needed here.

   Host page (consola) is already dark (#0C0A1E) with an ambient starfield, so
   the section paints NO solid background — the starfield shows through, like
   every sibling .sec. (The standalone package sets `background: var(--bg)`;
   that line is intentionally omitted here per the package's own guidance.)
