/* ==========================================================================
   QMS design system - light/dark, desktop-first with a mobile drawer.
   Same approach as GLP-Won: tokens on :root, redefined for the dark theme,
   no CDN, no JS framework.

   Light is the LIVE TULA brand (livetula.com/style-guide): Navy #002F3F and
   Green #128040 as the primaries, Orange #E66E17 and Light Blue #EAF6FA as
   the secondaries, Poppins throughout - SemiBold headlines, Regular all-caps
   sub-headlines, Bold section headlines, Regular paragraphs, navy text except
   on a dark ground.

   Dark is the same system on a Tron grid: near-black blue, cyan light lines,
   neon status inks, a glow where light mode has a shadow.
