+#
+# 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.
