We will introduce a new module mediawiki.action.styles which provides styling for all the action= URIs (with the exception of action=view). This will keep styles needed for pages such as action=info, action=protect, action=edit, action=preview, action=delete and action=watch separated from the critical path, as well as provide better support in skins such as Minerva that do not provide such styles for performance reasons.
- A module mediawiki.action.styles exists
- The module should load on all skins and have targets mobile and desktop.
- Relevant styles from the legacy feature are moved to the mediawiki.action.styles module organized and documented to which actions they apply to.
