 - [Pool Card Sizing](./devlog/2025-12-18-042500_pool_card_sizing.md): Completed. Fixed "enormous" card bug in horizontal pool by enforcing percentage-based height constraint.
 - [Final Pool Layout Fix](./devlog/2025-12-18-043500_pool_sizing_final.md): Completed. Overhauled flex layout for Horizontal Pool to ensure card images scale 1:1 with panel height during resize, removing layout-blocking transitions.
 - [Pool Overflow Constraint](./devlog/2025-12-18-044500_pool_overflow_fix.md): Completed. Enforce flex shrinkage with `min-h-0` and `overflow-hidden` to strictly bind card height to resizeable panel.
+- [Resize Persistence](./devlog/2025-12-18-050000_resize_persistence.md): Completed. Implemented `localStorage` persistence for Sidebars and Pool Panels in both Draft and Deck Views.

+# Work Plan - Persist Resize State
+
+## Request
+The user wants resized areas (sidebar and pool) to be remembered (persisted) so they reopen with the same sizes.
+
+## Changes
+- **DraftView.tsx**:
+    - Updated initialization of `sidebarWidth` state to read from `localStorage.getItem('draft_sidebarWidth')`.
+    - Added `useEffect` to save `sidebarWidth` to `localStorage` whenever it changes.
+    - Verified `poolHeight` persistence logic already exists.
+
+- **DeckBuilderView.tsx**:
+    - Updated initialization of `sidebarWidth` and `poolHeightPercent` to read from `localStorage` keys `deck_sidebarWidth` and `deck_poolHeightPercent`.
+    - Added `useEffect` hooks to persist both values to `localStorage`.
+    - Added `useEffect` to imports (fixed lint error).
+
+## Verification
+- **Test**: Refreshing the page after resizing the sidebar or pool panel should restore the previous dimensions exactly.
