/* Cron Expression Generator & Explainer — content styles.
   Prefix: --cron-  /  .cron-

   Reference point: a schedule readout, not a builder form — one text
   input, a plain-English sentence, a field-by-field table, and an ordered
   list of upcoming run times. Seventh distinct developer-cluster layout
   this build loop: prose explanation + table + list, not a card grid,
   canvas, split pane, three-card anatomy, highlighted editor, or results
   table alone.

   THIS FILE STYLES THE CONTENT AREA ONLY. Chrome is owned by chrome.css. */
