PerformanceBlock is the heart of the canvas:
- Status palette via CSS tokens (D21) — one class per booking_status enum value
- Cancelled hatch overlay + line-through (D5)
- Trashed-artist dashed border + ⌂ overlay icon (D27)
- Conflict ring + glow when warnings.includes('overlap') (D5)
- Capacity icon driven by evaluateCapacity() with warn/critical levels (D25)
- B2B left/right dots (D26 — 3-min threshold)
- Cascade-pulse class fired by parent on cascaded[] non-empty (D18)
- aria-label structure per D20: artist, stage, time window, status, advancing
- tabindex 0 + Enter/Space → select; Delete → emit delete
StageRow positions blocks by lane_resolved (D19) — server is authoritative.
StageHeaderCell uses Vuexy VMenu pattern for the per-stage actions.
EmptyDayState routes the user to LineupMatrix when no stages are active.
