# 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)
# - nowasm:         [UNSUPPORTED] removes all WebAssembly from builds including 
#                   ffmpeg, ffprobe and SQLite (instead falling back to modernc).
