-# --- PERFORMANCE START --- #
-# The performance team would like to monitor some files to understand
-# when performance-impacting changes occur. Our intent is not to block
-# these changes (for now) but to be aware of them. Please let us know
-# if the CODEOWNERS system makes this impractical. We're available at
-# #perf-android-frontend on Matrix.

-# The perf team is relying on CODEOWNERS to catch regressions. If
-# there is a single syntax error in the file, no rules will work.
-# Therefore, we make the Perfomance team code owners of this file.

-# or code that monitors for perf regressions. This is our main way to own code
-# because it's simpler and less fragile than listing many specific files to own.
