Key Recommendations

• Use <script setup lang="ts"> for all components
• Prefer ref() over reactive() for declaring state
• Use type-based prop declarations with interfaces
• Use defineModel() for v-model (3.4+)
• Destructure props reactively (3.5+) for cleaner code
• Extract composables for reusable stateful logic
