/* ============================================================================
   Codespark Infotech — "Meridian Noir"
   ----------------------------------------------------------------------------
   A dark, restrained skin over meridian.css. Layout and structure live there;
   this file swaps the palette and surfaces:

     · near-black ground, three layered greys, 1px hairlines at low opacity
     · ONE accent: the logo's orange, kept for the primary CTA, the single
       highlighted headline word, the meridian ticks and the overlap bar
     · no category colours: icons, stripes and tags are monochrome
     · display type set in Instrument Sans 600, tight-tracked, with a
       white-to-grey gradient on the big headlines

   Everything here is static CSS: it renders the same with JavaScript off.
