# Frontend API Instructions

## Scope
- Applies to API calls in `src/lib/api/api.ts` and feature-level data hooks.

## Rules
- Keep axios-based API calls centralized in `src/lib/api/api.ts`.
- Map backend response shapes to frontend-friendly models in hooks or API mappers.
- Follow existing tickets pattern: `api.ts` + feature hook (`useX`) + presentational components.
- Use optimistic updates carefully; ensure API failures do not leave inconsistent UI state.
- Keep request payload keys aligned with backend contract (`section_id`, `position`, etc.).

## Error Handling
- Surface recoverable errors to the user with clear toast messages.
- Avoid silent failures for create/update/delete flows.
