/**
 * Seeds the Artist & Timetable fixture for an existing festival with
 * three sub-events (e.g. Echt Feesten 2026 → Vrijdag/Zaterdag/Zondag).
 *
 * Reproduces the prototype audit fixture as closely as possible:
 * - 4 stages on the festival
 * - 4 stages × 3 sub-events = 12 stage_days rows
 * - 4 genres, 6 master artists with default genre + draw
 * - 12 engagements with status mix (Draft 1, Requested 2, Option 3,
 *   Confirmed 2, Contracted 3, Cancelled 1). Two artists each have
 *   two engagements (one per day) to exercise the multi-engagement
 *   case (D17).
 * - 13 performances; one parked (stage_id=null); a B2B pair within
 *   3 minutes on the same stage/lane to seed Session 4 frontend dev.
 * - One ArtistContact per artist (tour-manager role).
 *
 * advance_sections seeding lands in Session 3 with the form-builder
 * integration.
