Declare navigation, page metadata, lazy loaders, and keep-alive policy in one registry. Retain primary iframe pages until a continuous inactive TTL expires and expose typed show, hide, and unload events through the Page SDK.
Move business-aware components out of the UI primitive directory, migrate views and Host dialogs to variant primitives and local Tailwind classes, and remove the global component style layer. Keep native dialogs inside the overlay flex context so they remain centered.
Cover iframe expiration, lifecycle dispatch, UI dependency direction, and global style ownership with focused tests.
- opt service and settings pages into document retention
- preserve iframe identity and local Solid state across navigation
- cap retained documents with deterministic LRU eviction
- deliver activate, deactivate, and dispose lifecycle messages
- reject commands emitted by inactive page documents
- expose page activity as a Solid accessor
- test retention, recreation, eviction, and invalid limits
