+- The puppy's name and birthday are a shared profile stored on the host
+  (`GET`/`PUT /api/config`), so a new device picks them up automatically instead
+  of being configured per-client. The client caches the last-seen values in
+  `localStorage` for offline/instant paint and reconciles with the server by
+  last-write-wins on `updatedAt`. The age shown in the header (in weeks and
+  months) is derived from the birthday.
 
 A status pill in the header shows `syncing…` / `synced 2m ago` / `pending` /
 `sync error` / `offline`. Tap it to force-sync.
