📋 Decision Context

Question:

How to persist AI panel footer height across sessions?

Task: Not specified

🎯 Decision Made

Chosen:

Flash-persistence for AI panel footer height with autoFlashState

Options Considered:

1. Use localStorage manually
2. Use NGXS state management
3. Use session storage
4. Implement flash-persistence with autoFlashState
5. Store in backend database

💭 Reasoning

Following the theme-system flash-persistence integration pattern documented in @editor2/docs/english/GoGrab-Space/theme-system/flash-persistence-integration.md. Used autoFlashState from @storage-system with: (1) database: 'ai-panel' for organized storage, (2) collection: 'ui-preferences' for UI state, (3) priority: 'normal' since it's a UI preference not critical, (4) ttl: 90 days for long-term user preference, (5) debounceMs: 500ms to avoid excessive writes during drag. This provides instant restoration on page load, cross-tab sync, and automatic persistence. The footer height is saved during resize and restored in ngAfterViewInit.
