# frozen_string_literal: true

# This contains two patches to make sprockets more tolerable in dev
#
# 1. Stop computing asset paths which triggers sprockets to do mountains of work
#     All our assets in dev are in the /assets folder anyway
#
# 2. Stop using a concatenator that does tons of work checking for semicolons when
#     when rebuilding an asset
