/* World Time Zone Meeting Planner — content styles.
   Prefix: --tz-  /  .tz-

   Reference point: a 9-row city table with a per-row working-hours
   status is the centerpiece and the whole point — not a hero figure,
   since there's no single "the answer", only a table to scan for green
   rows. First reference-cluster tool built this loop.
