Icons

Theme Cupertino has built-in support for two icon packs — Simple Icons and Bootstrap Icons. They are enabled by default. You need to head to their docs for usage.

However, if you really don't need them, they can be disabled by setting:

_config.cupertino.yml

simple_icons: false
bootstrap_icons: false

Theme Cupertino requires Bootstrap Icons to display some icons of the UI, don't turn it off unless you know what exactly you're doing.
