   Loomiel Radar Loader — standalone stylesheet
   ───────────────────────────────────────────────────────────────────
   Drop-in loading indicator that matches the Loomiel brand: terminal
   green, monospace caption, a slow sweep wedge that evokes "narrative
   formation scanning."

   Markup:
     <span class="loomiel-radar loomiel-radar--md">
       <span class="lr-cross"></span>
       <span class="lr-sweep"></span>
       <span class="lr-ping"></span>
       <span class="lr-dot"></span>
     </span>
     <span class="loomiel-radar-caption">Scanning</span>

   Sizes: --sm (40 px), default (72 px), --lg (112 px).

   --font-mono fallback: 'JetBrains Mono' if --font-mono CSS var is
   not provided by the host page.
