 - [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.
+- [Resolve 413 Errors](./devlog/2025-12-18-112633_resolve_413_errors.md): Completed. Updated Helm ingress annotations and server limits to allow unlimited upload size.

+# Resolve 413 Request Entity Too Large Errors
+
+## Objective
+Fix the "413 Request Entity Too Large" errors occurring during large uploads or requests after application deployment.
+
+## Changes
+1.  **Helm Chart Configuration (`helm/mtg-draft-maker/values.yaml`)**:
+    *   Added Nginx Ingress annotation `nginx.ingress.kubernetes.io/proxy-body-size: "0"` to disable the body size limit check at the ingress level.
+
+2.  **Server Configuration (`src/server/index.ts`)**:
+    *   Increased `maxHttpBufferSize` for Socket.IO to 1GB.
+    *   Increased `express.json` body parser limit to 1000MB to support large JSON payloads (e.g., extensive card lists).
+
+## Verification
+*   **Infrastructure**: Ensure the application is redeployed with the updated Helm chart for the ingress annotation to take effect.
+*   **Application**: Verify that large payloads can be sent to the server without triggering 413 errors.
