recursive-nest

A platform sandbox app that embeds itself inside itself, recursively, via the <poe-app> custom element. Each level shows its depth, its instance id, and the list of members currently in that nested store, so you can visualize how deeply the app-embedding mechanism works and how multi-user presence propagates across levels.

What you can do

• Pick a child depth with the number input and watch a new <poe-app> mount inline below the controls.
• Inspect each level — every nested instance shows its own depth badge, instance id, and member chips.
• Verify cross-level presence — joining a deep nested instance updates the member list at that level while the parent levels stay independent.
• Reach a leaf — at max depth the child slot renders a plain "leaf" placeholder instead of recursing further.

Why this app exists

This is a platform test app for nested <poe-app> embedding. It is the simplest way to confirm that arbitrary-depth child apps, independent synced-store instances per level, and bidirectional sandbox communication all still work after platform changes.
