// ── Core's own engagement triggers ─────────────────────────────────────────
//
// ENGAGEMENT.md §4.3 and Phase 2. The twin of config/coreStreams.js, and
// deliberately the SAME FIVE IDS — that is the org lead's §7.2 decision, taken at
// the start of this phase: **one namespace.** A trigger is not a second thing
// standing next to a stream; it is a payload contract attached to an id that may
// also carry a subscription toggle. `news.post` names one event, whether the
// question being asked of it is "may I push this?" or "what may a template
// interpolate?".
//
// What that buys, concretely: `notification_channel_prefs.stream_id` (§4.5) stays
// single-keyed. Under two namespaces it would have needed a `kind` discriminator
// in its primary key, and `news.post` would have named two different things
// forever.
//
// What it costs is the rule enforced in registries.js: an id has ONE owner across
// both facets, so a module cannot attach a payload contract to another module's
// stream, and core cannot attach one to a module's. Core's five ids below are
// already core's five streams, so all five are the same-owner upgrade case.
//
// **These declare; nothing here emits yet.** Phase 2 is the contract only — the
// Team pipeline keeps its own hardcoded mail until Phase 6 migrates it onto the
// engine, and this file is what it migrates ONTO. Registering the declarations a
// phase early is the same decision registerCore() has always taken: a registry
// whose first real exercise is a module is a registry that has already drifted.
//
// Every variable carries an `example`, and that is required rather than
// decorative (§4.3 property 3). It is what lets the template editor preview and
// test-send without a live game event, which is the reason template systems go
// untested.
