 # Available Go build tags, with explanation, followed by benefits of enabling it:
-# - kvformat:       enables prettier output of log fields                       (slightly better performance)
-# - timetzdata:     embed timezone database inside binary                       (allow setting local time inside Docker containers, at cost of 450KB)
-# - notracing:      disables compiling-in otel tracing support                  (reduced binary size, better performance)
-# - nometrics:      disables compiling-in otel metrics support                  (reduced binary size, better performance)
-# - noerrcaller:    disables caller function prefix in errors                   (slightly better performance, at cost of err readability)
-# - debug:          enables /debug/pprof endpoint                               (adds debug, at performance cost)
-# - debugenv:       enables /debug/pprof endpoint if DEBUG=1 env during runtime (adds debug, at performance cost)
-# - moderncsqlite3: reverts to using the C-to-Go transpiled SQLite driver       (disables the WASM-based SQLite driver)
