- Drop unused `letterSpacing: 0.2` from TH_SX in both table cards
(HTML mockup has no letter-spacing on headers)
- Move `eventStatusTone` from EventsCard to dashboardVisual.ts
for symmetry with `eventTypeTone` (single source of tone semantics)
- Drop unused `columnWidths` prop and `widthsFor` override branch
in BrokerDashboardTableSkeleton (no caller passes it)
- Drop redundant `role="presentation"` on skeleton wrapper
(rows already carry `aria-hidden="true"`)
- Drop unused `TypeTone` import from EventsCard after moving
eventStatusTone out
