Detailed Description

Handle returned by Layer::add, carrying the assigned element id.

Provides chained post-registration mutations — relation, visibility, z-order — without requiring the caller to keep the id in a separate variable before acting on it.

Slot holds a non-owning reference to its Layer. It must not outlive the Layer. The recommended pattern is to extract the id immediately after configuration is complete and store that instead:

const uint32_t id = layer.add(std::move(el))
    .relate_to(parent_id)
    .hidden()
    .id();

When the id is not needed, Slot converts implicitly to uint32_t so existing callsites (el.element.id = layer.add(...)) compile unchanged.
