+# Task: Improve UI Surface Contrast
+
+## Goal
+
+Increase contrast between the app background, panels, and form controls so inputs are easier to identify against white or near-white surfaces.
+
+## Feature Spec
+
+`docs/FEATURES/platform-scaffold.md`
+
+## Scope
+
+- Update the shared frontend color tokens.
+- Configure Vuetify to use the Socialize light theme colors.
+- Add shared form control and surface defaults for native and Vuetify controls.
+- Avoid feature-specific behavior changes.
+
+## Likely Files
+
+- `frontend/src/assets/main.css`
+- `frontend/src/main.js`
+
+## Validation
+
+```bash
+cd frontend
+npm run build
+```
