/* Cryptographic Hash & Checksum Calculator — content styles.
   Prefix: --hc-  /  .hc-

   Reference point: a checksum verification table — one row per algorithm,
   because that's genuinely how these tools get used (computing all the
   common algorithms at once to match whatever a download page happened to
   publish). Sixth distinct developer-cluster layout this build loop: a
   results table, not a card grid, canvas, split pane, or single column.
