Overview

2.4-C: Metrics subconfig. The headline knob is ‘path_templater`, which collapses raw request paths to low-cardinality templates for the per-route latency histogram (operators with Rails-style routes plug in their own templater). `enabled` flips the new 2.4-C histogram/gauge surface as a whole — counters in the legacy surface (requests, bytes_read, …) keep emitting regardless.
