The focus-management section is especially important. Replacing part of a page visually does not guarantee that keyboard or screen-reader users know where the new content appeared. Moving focus to a result heading makes the enhanced flow much clearer.

Time handling is easy to underestimate in a distributed limiter. If application servers calculate refills using their own clocks, clock skew can produce inconsistent decisions. Keeping time calculation close to the authoritative Redis state makes the behavior easier to reason about.

Bloom filters are an interesting part of the LSM design. They can avoid many unnecessary table lookups, but they also introduce memory costs and false positives. Choosing the right filter size becomes another workload-dependent trade-off.

I like the distinction between errors and warnings. Missing keys should block deployment, while long translations should trigger visual review rather than automatically fail. Different languages should not be forced into limits designed around English.
