-# Modern builds target recent browsers supporting the latest features to minimize transpilation, polyfills, etc.

 # - released in the last 7 years + current alpha/beta versionss
-# - with global utilization at or above 0.05%
+# - with global utilization above 0.05%
-# - exclude dead browsers (no security maintenance for 2+ years)
+# The lattermost query ensures that support for popular old browsers is not dropped too early
-# - exclude Opera Mini which does not support web sockets
+# (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.
