== Background
Currently night mode is only available on the mobile site. As we pivot to desktop, we need to make a key technical decision to decide how we approach configuration in Vector (T359606). Without this technical decision, we will not be able to maintain a consistent night mode across skins.
In T357077 we explored different options for sharing code and created an [[ https://gerrit.wikimedia.org/r/c/mediawiki/skins/Vector/+/1009394/2/doc/adr/0004-code-sharing-between-vector-and-minerva.md | ADR to document our findings ]] - we now need to make a decision.
== User story
As a developer I need to understand how PHP code should be shared between Vector and Minerva to help me work on new feature requests.
== Requirements
See acceptance criteria.
== Design
No design needed.
== Acceptance criteria
[] The ADR is reviewed by the web team (developers, engineering manager and PM) and a decision is made on how we want to proceed
[] The ADR should be marked as accepted.
== Communication criteria - does this need an announcement or discussion?
No
== Sign off steps
The decision is fed back into https://phabricator.wikimedia.org/T357077 and that ticket is made ready for estimation.
