Most features have a desktop view and a phone view, and until now each
carried its own copy of the feature's logic, so a fix on one side drifted
away from the other. With the logic moved into one shared hook per
feature, scripts/feature-pairs.json names every feature with its hooks
and the desktop and phone files that run on them.
lint:pairs fails when a listed view stops importing one of its pair's
hooks (a type only import does not count), when a listed file is gone,
when a hook sits in a view layer rather than under components, hooks,
utils or the folder of a page under pages/, and when a file under
src/mobile/screens is in no pair and not under mobileOnly with the
reason it has no twin. A new phone screen is so either wired to the
desktop feature's hook or marked as phone only on purpose. lint:dup
catches the copies that look alike; this one catches the copies written
anew.
The manifest starts with 120 features and 62 phone only screen files,
each with the reason it stays on the phone alone.
client/CLAUDE.md says how to change a feature, add one with both views
and add a phone screen.
