  * Built-in “faux spells”: same NoteList + filters as kind-777 spells. The Spells page uses live
  * `subscribeTimeline` (same as Following) so the first relay results stream in immediately instead of
  * waiting for every relay to EOSE on a one-shot query.
+ *
+ * **Why faux feeds can feel slow:** each timeline shard opens live REQs over the prioritized relay
+ * stack (see {@link applyFauxSpellCapsToSubRequests}). The **interests** spell uses **one** shard: all subscribed
+ * topics go in a single `#t` filter (NIP-01 OR semantics). The notifications spell uses a narrow
