// System capabilities: privileged host services a first-party/system plugin (the built-in admin
// screens are the reference consumer) needs but an ordinary domain plugin does not — the Ory admin
// clients and the instant-revoke hook. Exposed on ctx.system and re-exported via #plugin-api.
//
// Every field is optional: it is present only when the host wired that dependency (Ory configured,
// denylist enabled), and ctx.system itself is undefined when the host wired none. A plugin must
// treat each as optional and degrade when absent — the host does not fail a request over it.

// Grouping criterion (keep this cohesive — it's a contract, so the "no catch-all bucket" rule that
// governs folders governs this bag too): every field is a *privileged, host-owned, wire-dependent*
// capability for administering Plainpages' own identity/permission stack. Add a field only when it
// meets all three; if unrelated privileged concerns accrete (mailer, metrics, flags), sub-group
// rather than pile them in flat.
