+
+## Project Structure & Module Organization
+
+This is a React 18 administration application built with Vite. Application code lives in `src/`: route-level features are grouped in `src/pages/`, reusable UI in `src/components/` and `src/common/`, API clients in `src/api/`, and shared hooks and helpers in `src/hooks/` and `src/utils/`. Routing, layout, and state are maintained in `src/routes/`, `src/layout/`, and `src/store/`. Styles are primarily colocated Less files. Static assets belong in `src/assets/`; files that must be served unchanged belong in `public/`. The formula editor source and its built output are under `public/formula-editor/`.
+
+## Build, Test, and Development Commands
+
+- `npm ci` installs the exact dependency versions from `package-lock.json`.
+- `npm run dev` starts Vite with HTTPS and the API proxy configured in `vite.config.js`.
+- `npm run build` creates a production bundle in `dist/`.
+- `npm run build:dev` builds with Vite's development mode settings.
+- `npm run preview` serves the production bundle for a local smoke test.
+- `npm run lint` runs ESLint on `src/` and automatically fixes supported issues. Review the resulting diff.
+
+## Coding Style & Naming Conventions
+
+Follow the existing JavaScript/JSX style: two-space indentation, single quotes, no semicolons, and functional React components. Use `PascalCase` for component names, `camelCase` for functions and variables, and `useXxx` for hooks. Existing feature folders generally use lowercase or kebab-case names and expose entry points as `index.jsx`. Prefer the `@/` alias for imports rooted at `src/`. ESLint extends the recommended React and React Hooks rules; keep hook dependency arrays accurate.
+
+## Testing Guidelines
+
+No automated test framework or coverage threshold is currently configured. For every change, run `npm run lint` and `npm run build`, then smoke-test affected routes with `npm run dev`. Verify editor changes with realistic content, uploads, and API failure states. If adding tests, colocate them as `*.test.jsx` or `*.test.js` and add the associated runner command to `package.json`.
+
+## Commit & Pull Request Guidelines
+
+Recent history follows Conventional Commit-style prefixes such as `feat:`, `fix:`, `refactor:`, and `chore:`. Keep the subject concise, imperative, and focused on one change. Pull requests should explain the user-facing impact, list validation performed, link the relevant issue, and include screenshots or recordings for UI changes. Call out API, proxy, dependency, or configuration changes explicitly; never commit credentials or environment-specific secrets.
