/* Service Times — the board.
*
* One card per campus, one row per service, and a mark on any service that
* production has to treat differently this week. Everything is drawn from the
* server's SSE state so every booth sees the same marks at the same moment;
* nothing here talks to the website.
*
* Marking lives in the tile body, not the title bar, because the bar folds
* away in fullscreen and on an auto-hiding dashboard — a control an operator
* needs mid-service may not disappear with it.
