+# Work Plan - Set Default Slider Values to Minimum
+
+## Request
+Set the default value for card size sliders to their minimum setting across all views:
+1. Cube Manager (Draft Management)
+2. Draft View (Online Draft Pick)
+3. Deck Builder
+
+## Changes
+- **CubeManager.tsx**: Changed default `cardWidth` from `140` to `100`.
+- **DraftView.tsx**: Changed default `cardScale` from `0.7` to `0.5`.
+- **DeckBuilderView.tsx**: Changed default `cardWidth` from `150` to `100`.
+
+## Verification
+- Verified that the new default values match the `min` attribute of the respective range inputs.
+- Verified that no other sliders exist in the codebase.
