phosphor-overlay

Per-screen layer-shell shell hosts with named slot vocabulary.

Helper layer on top of phosphor-layer, phosphor-surfaces, and phosphor-animation. Given a consumer-provided surface factory, ShellHost owns the per-screen layer-shell shell lifecycle (create, destroy, rekey), the slot map keyed by consumer-chosen slot names, animator-driven slot hides, and per-role animator config registration. Knows nothing about zones, layouts, or specific content; consumers wire their own slot vocabulary through callbacks.
