/* =============================================================
   LONGLAST LABS — SHARED NAVBAR COMPONENT
   Used by: labs, use-cases, apex, intelligence, explore-intelligence,
   mrvl-documentation, quant-model.
   Self-sufficient: safe on pages that do not load style.css.
   On pages that do load style.css, link this file AFTER it.

   Variants (combine on the <nav> element):
     .labs-nav                 dark floating pill (default, 70px, fixed)
     .labs-nav.inverted        light-background styling
     .labs-nav--compact        smaller bar for doc/dashboard pages
     .labs-nav--static         in-flow instead of fixed (sits above page topbars)
