-[modern]
-# Support for dynamic import is the main litmus test for serving modern builds.
-# Although officially a ES2020 feature, browsers implemented it early, so this
-# enables all of ES2017 and some features in ES2018.
-supports es6-module-dynamic-import
-
-# Exclude Safari 11-12 because of a bug in tagged template literals
-# https://bugs.webkit.org/show_bug.cgi?id=190756
-# Note: Dropping version 11 also enables several more ES2018 features
-not Safari < 13
-not iOS < 13
-
-# Exclude KaiOS, QQ, and UC browsers due to lack of sufficient feature support data
-# Babel ignores these automatically, but we need here for Webpack to output ESM with dynamic imports
-not KaiOS > 0
-not QQAndroid > 0
-not UCAndroid > 0
-
-# Exclude unsupported browsers
-not dead
-
-[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.
-unreleased versions

 ---
 
 # Remove vs Delete
-
 Remove and Delete are quite similar, but can be frustrating if used inconsistently.
 
 ## Remove
-
 Take away and set aside, but kept in existence.
 
 For example:
-
-- Removing a user's permission
-- Removing a user from a group
-- Removing links between items
-- Removing a widget
-- Removing a link
-- Removing an item from a cart
+* Removing a user's permission
+* Removing a user from a group
+* Removing links between items
+* Removing a widget
+* Removing a link
+* Removing an item from a cart
 
 ## Delete
-
 Erase, rendered nonexistent or nonrecoverable.
 
 For example:
-
-- Deleting a field
-- Deleting a value in a field
-- Deleting a task
-- Deleting a group
-- Deleting a permission
-- Deleting a calendar event
+* Deleting a field
+* Deleting a value in a field
+* Deleting a task
+* Deleting a group
+* Deleting a permission
+* Deleting a calendar event
 
 # Add vs Create
-
 In most cases, Create can be paired with Delete, and Add can be paired with Remove.
 
 ## Add
-
 An already-exisiting item.
 
 For example:
-
-- Adding a permission to a user
-- Adding a user to a group
-- Adding links between items
-- Adding a widget
-- Adding a link
-- Adding an item to a cart
+* Adding a permission to a user
+* Adding a user to a group
+* Adding links between items
+* Adding a widget
+* Adding a link
+* Adding an item to a cart
 
 ## Create
-
 Something made from scratch.
 
 For example:
-
-- Creating a new field
-- Creating a new value in a field
-- Creating a new task
-- Creating a new group
-- Creating a new permission
-- Creating a new calendar event
+* Creating a new field
+* Creating a new value in a field
+* Creating a new task
+* Creating a new group
+* Creating a new permission
+* Creating a new calendar event
