Signage had no agent guidance at all. Add a CLAUDE.md that records the
standalone-module architecture, that the parent ROADMAP.md and DESIGN.md are
authoritative, the ownership, branding, token, dark-mode, no-native-dialog and
plain-language rules, that display pairing is transitional until Stage 1
Settings -> Displays, and the branch-per-PR, no-push-to-main, no-release-tag
workflow.
The README listed a mobile management UI as out of scope, which contradicts
the design contract's responsive requirement; it is a Stage 1 deferral, and
now says so alongside how displays work today.
