/**
 * device-lines.ts, the one rendering of a paired-device list.

 * Every surface that lists devices (a /devices command family, a settings
 * device-management modal) renders each per-device token the same way
 * (name · created · last-seen · id), so no two of them drift. Pure over its
 * inputs and a `now` clock, so the formatting is testable without real time.
