/* shell/public/pages/online-history.css
 * Day-card visual scaffold for /online-history.
 *
 * NOT a v1 code copy — uses our own .oh-* class names (similar concept,
 * different selectors so Online History is module-isolated from Online Today).
 *
 * Mechanics still come from the shared tracker pieces:
 *   - .ot-bar-wrap        (flex sizing tied to --ot-bar-fill-width × --ot-zoom)
 *   - .ot-bar-scaler      (vertical hour ticks via ::before)
 *   - .ot-seg             (per-status segments, including hover tooltips)
 *   - .ot-drag-pan card   (horizontal scroll + click-drag pan + shared scrollbars)
 *   - .ot-hour-markers    (top hour labels)
 *
 * Counters in the header (right-aligned) replace the v2 right-side .ot-nums
 * column. First / Last seen sit alongside the counters and only render when
 * the day has timeline activity.
