# And here's the second place - this runs after we have both the current and
# base branch bundle stats, and will compare them to determine what changed.
# There are two configurable arguments that come from package.json:
#
# - budget: optional, set a budget (bytes) against which size changes are measured
# it's set to 350kb here by default, as informed by the following piece:
# https://infrequently.org/2021/03/the-performance-inequality-gap/
#
# - red-status-percentage: sets the percent size increase where you get a red
# status indicator, defaults to 20%
#
# Either of these arguments can be changed or removed by editing the `nextBundleAnalysis`
# entry in your package.json file.
