EnableNotifications subscribes the owner's device with the public VAPID
key and stores it; sw.js receives pushes and opens /defects on click;
`pnpm vapid:keys` mints the key pair.
Overlay each filed defect as a red dot inside its section box with a
diagonal date label; cap visible dots and collapse the remainder to a
"+N more" using the authoritative per-section counts (T6).
Add an `overlay` scoped slot to BoardView (C2) so the dashboard can layer
dots without forking the board definition (F1); the reporting view leaves
it empty. DotMap groups the bounded feed by section and the /defects page
wires both endpoints.
Drop the two-subdomain split (ADR 0004): report at /, view defects at
/defects, with a shared layout + header nav. Renames the dashboard page to
defects.vue and updates plan/README. Transparency over separation now that
auth gates everyone, and it removes the Coolify two-domain routing question.
