//
// `4byteTracer` returns a count of `<selector>-<callDataSize>`
// occurrences seen during the trace. Keys look like
// `"0xa9059cbb-68"` (transfer with the standard 4-byte selector
// plus a 64-byte argument tail); values are the count of times
// that signature was invoked. Useful for high-level "what got
// called" summaries without descending into per-frame detail.
