Click a tile to run it. Only one demo runs at a time. Demos are sandboxed and lifecycle-managed to keep the shell fast.
Runner
No demo loaded.
Policy
- Isolation: iframe sandbox keeps demo JS out of the shell.
- Lifecycle: previous demo is destroyed (DOM + memory pressure reduced).
- Performance: we measure load timing for visibility.
- Motion: no autoplay; demos only load on explicit click.
Tier-2: Embedded demo (placeholder)
Medium demo embedded via iframe to /demos/<name>/ once you add demos pipeline.

Tier-3: Heavy demo (placeholder)
