Your certificate chain is about to get heavy
An ML-DSA signature is not a drop-in for an ECDSA one — it is roughly an order of magnitude larger, and a chain carries several. Here is what that does to TLS handshake latency on a lossy mobile link, what it does to firmware images with a fixed signature slot, and the three places I have seen it break before anyone had a chance to plan for it.
Replace this with the real post. Everything below is here so you can judge the reading measure, the leading, and how the mono metadata sits against body copy at length.
The interesting number is not the signature size on its own. It is the size multiplied by the depth of the chain, multiplied by the probability that the whole thing no longer fits in the initial congestion window.
