-[legacy]
-# Legacy builds are served when modern requirements are not met and support browsers:
-# - released in the last 7 years + current alpha/beta versionss
-# - with global utilization above 0.05%
-# The lattermost query ensures that support for popular old browsers is not dropped too early
-# (e.g. IE 11, Android 4.4, or Samsung 4).
-#
-# In addition, legacy browsers must support some minimum features that cannot be polyfilled:
-# - ES5 (strict mode)
-# - web sockets to communicate with backend
-# - inline SVG used widely in buttons, widgets, etc.
-# - custom events used for most user interactions
-# - CSS flexbox used in the majority of the layout
-# Nearly all of these are redundant with the above rules.
-# As of May 2023, only web sockets must be added to the query.
