/* ─── BROWSER FRAME COMPONENT ─────────────────────────────────────────
   Usage:
     <div class="browser-frame af1" style="--chrome: #4B6EE6;">
       <div class="b-chrome"><span class="b-dot"></span>×3</div>
       <img class="b-image" src="painting.jpg" alt="">
     </div>

   • Set --chrome on the element to pick the bar colour.
   • Drop any raw image in as .b-image — height stays auto,
     so the frame wraps the image's natural aspect ratio.
   • Use .b-placeholder (with --ratio and --ph vars) until
     a real image is available.
