- Arraylake -> native S3 (spring-data/hf-bucket-arraylake-write-performance-s3-native) now succeeds on the Space (0.9s vs 17s for Arraylake->HF bucket on a 1h x 2 var slice, zero-a10g), so remove the 'does not work yet / unticked by default / AccessDenied' notices in app.py and README
- Tick all three CheckboxGroup values by default (ARMS) and isolate HF bucket as slow half in INTRO/README
- Drop 'All runs this session' history dataframe — single 'Results' table showing all three arms is enough
Tick the native-S3 control arm alongside the two icechunk arms, and
reword the concurrency log line to name the zarr async concurrency.
