What works offline (after save)

• Mission, Legs, Results, and Schedule tabs from embedded race payload
• 17-leg schedule, assignments context, and leg benchmarks
• Leg route overlays and elevation profiles
• Service-worker cached shell, CSS, and Mission Control JavaScript

What may degrade

• Basemap tiles may be blank offline; leg route line and elevation profile remain.
• Live cumulative place/gaps unavailable without cached snapshot.
• MapLibre library requires prior CDN cache save on Wi-Fi.
• Basemap tiles may be blank; route geometry overlay should still render after pack save.
• MapLibre CDN dependency — flag in readiness report.
• Benchmark cards may show unavailable copy when historical data missing for a leg.

Release blockers (current build)

• None
