/* Audio File Size Calculator — content styles.
   Prefix: --as-  /  .as-

   Reference point: a warmer, studio-adjacent neutral than
   `file-transfer-and-render-time-calculator`'s cooler grey — the
   second `files-media`-cluster tool this loop, deliberately
   differentiated so the cluster doesn't read as one repeated palette.
