/* ============================================================
   PULSETECH DOCS: refined terminal
   ============================================================
   Ports the design language of mypulsetech.com (see assets/pulse.css)
   onto Material for MkDocs, adapted for long-form reference reading:

   - Marketing site shouts: 76px display type, full-page scanlines, glow.
   - Docs whisper: the terminal vocabulary moves into the *chrome*
     (nav, labels, code frames, callout titles) and stays out of body copy,
     which keeps its comfortable Inter and generous line-height.

   Loaded after extra.css, so it wins ties. Delete this file and its
   extra_css entry in mkdocs.yml to revert the whole look.
   ============================================================ */
