//! Thread-local stack of instrumented-function names used to attribute SQL
//! queries and HTTP requests to the innermost measured function (the "Source"
//! column). The meta crate carries no SQL or HTTP front-end, so these compile
//! to no-ops; the call sites in the measurement guards stay in place so the
//! guard code mirrors the main crate.
