From ecf7e88bb41162e00ebc0e68ca4ced394e7f5132 Mon Sep 17 00:00:00 2001 From: Lucas 'Paperboy' Rose-Winters Date: Thu, 23 Oct 2025 10:34:47 +1100 Subject: [PATCH] feat: complete Task 1.8 - Layout Persistence System MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Created LayoutPersistence class with full save/load/import/export - Implemented debounced auto-save (500ms after changes) - Added manual save, export (JSON download), import (file picker) - Added reset to default with confirmation - Comprehensive dashboard validation - Event-driven architecture with onChange listeners - Save status indicator with real-time updates - Event log for all persistence operations - Auto-load saved layout on startup -
