An interactive JSONPath REPL that runs multi-step query pipelines against any JSON. Write one JSONPath expression per line (e.g. $..book[?(@.price<10)] then $[0:5]) and see each step's matches with counts, paths, and values — plus a shareable URL that encodes your data and pipeline. Supports recursive descent ($..), wildcards ([*]), filters ([?(@.price<10)]), slices ([0:5:2]), and negative indices.
