// ─────────────────────────────────────────────────────────────────────────────
// FEED — the live event stream field (real-data ownership spec).
//
// This organ is WEBSOCKET-ONLY: it consumes $eventFeed from $stores/websocket
// (there is NO REST endpoint). The backend pushes a {"type":"Connected"} frame
// immediately on /ws open, then Heartbeats every ~5s, plus real lifecycle events
// (MemoryPromoted, MemoryPrOpened, TraceEvent, ...) as the brain works. The feed
// lays each NON-heartbeat event out as a row (type | id | payload summary) in a
// TextLayerPass over the observatory scene; clicking a row clears the feed.
//
// It was DOUBLY dead before the WS-guard fix in +layout.svelte (the old
// `!isMarketingRoute && !isImmersiveRoute` guard was always false, so the socket
// never connected on ANY route). It only lights up now that the socket connects.
//
// The 7-point organ contract proven here (real brain :3931 via the :5199 proxy):
//   1. REACHABLE — /dashboard/feed mounts a WebGPU canvas.
//   2. RENDERS REAL DATA — the app's OWN socket delivers real frames (Connected +
//      real lifecycle events); those events drive a non-black, genuinely-lit field
//      (max glyph luminance well above the background floor). No mock, no fake
//      "Live" badge over stale data.
//   3. ALIVE — the field animates at idle (per-glyph time wobble + reveal + scene),
//      no interaction required.
//   4. CRASH-FREE pick + hover — a hover sweep + a click grid (each a real
//      clearEvents on a row hit) never throw a page/WebGPU error, and the field
//      still renders afterward. pickAt mirrors the shader's aspect transform.
//   5. HONEST empty/connection state — with zero events the feed shows a calm
//      connection-state line ({"connected":..,"reconnecting":..,"events":0}),
//      never a broken/black surface and never fabricated rows.
