/**
* Tracks whether each light-DOM slot carries meaningful consumer content.
*
* Presence is seeded directly from the host's children during connection, before Lit's first
* render, so declarative labels/adornments never flash through an empty state while waiting for
* `slotchange`. After render, one delegated listener on the render root keeps every slot name in
* sync. Reading light DOM also excludes a `<slot>` element's fallback children: fallback is
* component chrome, not consumer-provided slot presence.
*
* The controller intentionally answers only the generic presence question. Components whose
* default slot is an option/item collection keep their specialized assigned-element handler for
* identity, ordering, and mutation semantics.
