Review Comment:
   There’s one more thing that might be worth looking at: in `wait-storage.sh`, 
the PD REST address is derived from `pd.peers`, but in practice the script only 
checks the first peer.
   
   This works fine in the current compose example, but it still feels a bit 
fragile in a multi-PD setup. For example, during a fairly common rolling 
restart, a single-node upgrade, or when one PD node simply comes up more slowly 
than the others, if the first PD in the list is temporarily unavailable, the 
script will keep treating PD as not ready even if the other two PD nodes are 
already up and working normally.
   
   So I think a more reliable approach here would be either:
   - explicitly passing a PD REST endpoint, or
   - trying the peers from `pd.peers` in order instead of checking only the 
first one
   
   This may not cause an immediate problem in the default compose setup, but 
from a multi-PD robustness perspective, I think it’s still worth noting.
