/* ── Pixel Range ──────────────────────────────────
   Images: 27×10 track, 8×7 thumb (native pixels)

   HTML:
   <label class="px-range">
     <span class="px-range__label">Label</span>
     <span class="px-range__wrap">
       <span class="px-range__visual" aria-hidden="true">

   Add class "px-range--native" to <label> to show
   the raw range input instead of the pixel art.
