read_buf_cap is now the per-request LIMIT, not a preallocation: slots start at 16K, double when full (one-step sizing when a Content-Length declares the body), and keep their grown capacity for slot reuse. At the limit the refusal distinguishes oversized headers (431) from an oversized body (413). Unblocks A1: distd accepts multi-hundred-MB artifact uploads — preallocating that per slot was never an option. examples/1633 adds a body past the initial capacity echoing intact.
