# Implementation Plan for Issue #85

## Objective
Fix the dark mode brightness of the Premium and read-only banners, adjust the banner's corner radius, and fix the vehicle list scroll position upon data load.

## Key Files & Context
- `app/src/main/java/com/servicebook/ui/theme/Color.kt`
- `app/src/main/java/com/servicebook/ui/components/PaywallStatusCard.kt`
- `app/src/main/java/com/servicebook/ui/vehicles/VehicleListScreen.kt`

## Implementation Steps
1. **Tone down `tertiaryContainer` for dark mode:**
   In `Color.kt`, change `TertiaryContainerDark` from `Color(0xFF523F5F)` to `Color(0xFF332540)`.
2. **Bump the banner's corner radius:**
   In `PaywallStatusCard.kt`, change `shape = MaterialTheme.shapes.large` to `shape = RoundedCornerShape(24.dp)`. Add necessary imports (`androidx.compose.foundation.shape.RoundedCornerShape` and ensure `androidx.compose.ui.unit.dp` is present).
3. **Keep banner visible when data loads:**
   In `VehicleListScreen.kt`, after `val listState = rememberLazyListState()`, add:
   ```kotlin
   LaunchedEffect(state.isLoading, state.isReadOnly) {
       if (!state.isLoading && state.isReadOnly) {
           listState.scrollToItem(0)
       }
   }
   ```

## Verification & Testing
- Run `./gradlew testDebugUnitTest`
- Run `./gradlew recordRoborazziDebug` to update screenshot baselines, then `./gradlew verifyRoborazziDebug`.
- Run `./gradlew lintDebug ktlintCheck detekt`.
