// Owner display (v2) — Personal vs Workspace in cloud, Local in single-player.
//
// v1's scope stack (personal → org) collapsed to a single `Owner` axis: a
// connection / policy is owned by the `org` (tenant-shared) or by the acting
// `user`. The global "active owner" toggle has been retired: views no longer
// filter by a single ambient owner. Instead, read surfaces merge BOTH owners
// (atoms omit `owner`), and each row carries its own `owner` for grouping +
// badges. Owner stays real only at WRITE surfaces (policy writes, the run-panel
// address, create-target choices), where it is chosen explicitly per call.
//
// These helpers are display-only. Write paths must still resolve owners through
// the connection-owner helpers so local hosts clamp to one Local owner.
