/* Knight CTO — critical above-the-fold CSS.
   Loaded synchronously before paint. Contains ONLY what's needed to
   render the first viewport correctly (nav + hero on desktop, mobile
   pager hero on phones). Everything else lives in _shared.css and is
   loaded async via preload+onload to keep the critical request chain
   short. Keep this file under ~3KB. */
