+# YFPP Project Guidelines
+
+## Project Overview
+
+YFPP (Your Fucking Polling Place) is a static SPA hosted on GitHub Pages. It accepts a voter's registered address, queries the Google Civic Information API for upcoming election/polling data and the Open States API for representative data, and displays results with Mapbox directions. The site inserts the word "fucking" into polling place names via the `fucktify()` helper.
+
+## Code Style
+
+- **Language**: TypeScript (strict mode). All new files must be `.ts` or `.tsx`.
+- **React**: Functional components only. Hooks for all state and side effects. No class components.
+- **State management**: `useReducer` + React Context (existing pattern in `appReducer`). No external state libraries.
+- **Imports**: Use path aliases rooted at `src/` (e.g., `import helpers from 'helpers'`).
+- **Naming**: PascalCase for components and types, camelCase for functions/variables, UPPER_SNAKE_CASE for constants and action types.
+- **CSS**: SCSS modules colocated with components. Do not refactor existing styles unless explicitly requested by the project lead in a documented task or issue.
+
+## Architecture
+
+- `src/types/` — shared TypeScript type definitions (API responses, app state, actions)
+- `src/requests/` — API client functions (Google Civic, Open States, Mapbox)
+- `src/actions/` — reducer action handlers
+- `src/hooks/` — custom React hooks
+- `src/components/` — UI components, each in its own directory with colocated styles and tests
+- `src/helpers.ts` — utility functions (`fucktify`, `titlecase`, `concatStreetAddress`, etc.)
+
+## Build and Test
+
+- **Package manager**: pnpm (never npm or yarn)
+- **Build tool**: Vite
+- **Dev server**: `op run --env-file=".env.local" pnpm dev`
+- **Build**: `pnpm build`
+- **Unit/integration tests**: `pnpm test:unit` (Vitest + React Testing Library)
+- **E2E tests**: `pnpm test:e2e` (Playwright)
+- **Type check**: `pnpm tsc --noEmit`
+- **Lint**: `pnpm lint` (ESLint 9, flat config). Fix auto-fixable issues with `pnpm lint:fix`.
+- **Format**: `pnpm format:check` to verify, `pnpm format` to auto-format. Run lint and format checks before committing.
+
+## Conventions
+
+- **Environment variables**: Use `import.meta.env.VITE_*` (Vite convention). Never `process.env`.
+- **API keys**: Never commit secrets. Development uses 1Password CLI (`op run --env-file=".env.local"`) to inject secrets at runtime from 1Password references (`op://` URIs). Production builds use GitHub Secrets injected via GitHub Actions. Keys are in the client bundle (static SPA) — they must be restricted by domain/referrer in their respective dashboards.
+- **Error handling**: API failures must degrade gracefully. A failed representatives call must not block polling place results. If an API returns invalid data, log the error and display a user-friendly message indicating that some information may be missing. Dispatch granular errors per API call.
+- **No legacy libraries in new code**: No jQuery, lodash, moment.js, or prop-types. Use native JS/TS equivalents and TypeScript interfaces.
+- **Date handling**: Use `date-fns` instead of moment.js.
+- **Testing**: New code must include tests. Place test files alongside source files (`Component.test.tsx`). Use MSW for API mocking.
+- **Security**: Validate and sanitize all external data at system boundaries. Follow OWASP Top 10 guidelines. Use `encodeURIComponent` for URL parameters.

+## Prerequisites
-## Updating to New Releases
+- **Node.js** ≥ 22
+- **pnpm** ≥ 11
+- **1Password CLI** (`op`) — used to inject API keys at runtime
-Create React App is divided into two packages:
-
-- `create-react-app` is a global command-line utility that you use to create new projects.
-- `react-scripts` is a development dependency in the generated projects (including this one).
-
-You almost never need to update `create-react-app` itself: it delegates all the setup to `react-scripts`.
-
-When you run `create-react-app`, it always creates the project with the latest version of `react-scripts` so you’ll get all the new features and improvements in newly created apps automatically.
-
-To update an existing project to a new version of `react-scripts`, [open the changelog](https://github.com/facebook/create-react-app/blob/master/CHANGELOG.md), find the version you’re currently on (check `package.json` in this folder if you’re not sure), and apply the migration instructions for the newer versions.
-
-In most cases bumping the `react-scripts` version in `package.json` and running `npm install` (or `yarn install`) in this folder should be enough, but it’s good to consult the [changelog](https://github.com/facebook/create-react-app/blob/master/CHANGELOG.md) for potential breaking changes.
-
-We commit to keeping the breaking changes minimal so you can upgrade `react-scripts` painlessly.
-
-## Sending Feedback
-
-We are always open to [your feedback](https://github.com/facebook/create-react-app/issues).
-
-## Folder Structure
-
-After creation, your project should look like this:
-
-```
-my-app/
- README.md
- node_modules/
- package.json
- public/
- index.html
- favicon.ico
- src/
- App.css
- App.js
- App.test.js
- index.css
- index.js
- logo.svg
-```
-
-For the project to build, **these files must exist with exact filenames**:
-
-- `public/index.html` is the page template;
-- `src/index.js` is the JavaScript entry point.
-
-You can delete or rename the other files.
-
-You may create subdirectories inside `src`. For faster rebuilds, only files inside `src` are processed by Webpack.
-You need to **put any JS and CSS files inside `src`**, otherwise Webpack won’t see them.
-
-Only files inside `public` can be used from `public/index.html`.
-Read instructions below for using assets from JavaScript and HTML.
-
-You can, however, create more top-level directories.
-They will not be included in the production build so you can use them for things like documentation.
-
-If you have Git installed and your project is not part of a larger repository, then a new repository will be initialized resulting in an additional `.git/` top-level directory.
-
-## Available Scripts
-
-In the project directory, you can run:
-
-### `npm start`
-
-Runs the app in the development mode.
-Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
-
-The page will reload if you make edits.
-You will also see any lint errors in the console.
-
-### `npm test`
-
-Launches the test runner in the interactive watch mode.
-See the section about [running tests](#running-tests) for more information.
-
-### `npm run build`
-
-Builds the app for production to the `build` folder.
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.
-Your app is ready to be deployed!
-
-See the section about [deployment](#deployment) for more information.
-
-### `npm run eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
-
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
-
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
-
-## Supported Browsers
-
-By default, the generated project supports all modern browsers.
-Support for Internet Explorer 9, 10, and 11 requires [polyfills](https://github.com/facebook/create-react-app/blob/master/packages/react-app-polyfill/README.md).
-
-### Supported Language Features
-
-This project supports a superset of the latest JavaScript standard.
-In addition to [ES6](https://github.com/lukehoban/es6features) syntax features, it also supports:
-
-- [Exponentiation Operator](https://github.com/rwaldron/exponentiation-operator) (ES2016).
-- [Async/await](https://github.com/tc39/ecmascript-asyncawait) (ES2017).
-- [Object Rest/Spread Properties](https://github.com/tc39/proposal-object-rest-spread) (ES2018).
-- [Dynamic import()](https://github.com/tc39/proposal-dynamic-import) (stage 3 proposal)
-- [Class Fields and Static Properties](https://github.com/tc39/proposal-class-public-fields) (part of stage 3 proposal).
-- [JSX](https://facebook.github.io/react/docs/introducing-jsx.html) and [Flow](https://flow.org/) syntax.

-Learn more about [different proposal stages](https://babeljs.io/docs/plugins/#presets-stage-x-experimental-presets-).
-
-While we recommend using experimental proposals with some caution, Facebook heavily uses these features in the product code, so we intend to provide [codemods](https://medium.com/@cpojer/effective-javascript-codemods-5a6686bb46fb) if any of these proposals change in the future.
-
-Note that **this project includes no [polyfills](https://github.com/facebook/create-react-app/blob/master/packages/react-app-polyfill/README.md)** by default.
-
-If you use any other ES6+ features that need **runtime support** (such as `Array.from()` or `Symbol`), make sure you are [including the appropriate polyfills manually](https://github.com/facebook/create-react-app/blob/master/packages/react-app-polyfill/README.md), or that the browsers you are targeting already support them.
-
-## Syntax Highlighting in the Editor
-
-To configure the syntax highlighting in your favorite text editor, head to the [relevant Babel documentation page](https://babeljs.io/docs/editors) and follow the instructions. Some of the most popular editors are covered.
-
-## Displaying Lint Output in the Editor
-
-> Note: this feature is available with `react-scripts@0.2.0` and higher.
-> It also only works with npm 3 or higher.
-
-Some editors, including Sublime Text, Atom, and Visual Studio Code, provide plugins for ESLint.
-
-They are not required for linting. You should see the linter output right in your terminal as well as the browser console. However, if you prefer the lint results to appear right in your editor, there are some extra steps you can do.
-
-You would need to install an ESLint plugin for your editor first. Then, add a file called `.eslintrc` to the project root:
-
-```js
-{
- "extends": "react-app"
-}
-```
-
-Now your editor should report the linting warnings.
-
-Note that even if you edit your `.eslintrc` file further, these changes will **only affect the editor integration**. They won’t affect the terminal and in-browser lint output. This is because Create React App intentionally provides a minimal set of rules that find common mistakes.
-
-If you want to enforce a coding style for your project, consider using [Prettier](https://github.com/jlongster/prettier) instead of ESLint style rules.
-
-## Debugging in the Editor
-
-**This feature is currently only supported by [Visual Studio Code](https://code.visualstudio.com) and [WebStorm](https://www.jetbrains.com/webstorm/).**
-
-Visual Studio Code and WebStorm support debugging out of the box with Create React App. This enables you as a developer to write and debug your React code without leaving the editor, and most importantly it enables you to have a continuous development workflow, where context switching is minimal, as you don’t have to switch between tools.
-
-### Visual Studio Code
-
-You would need to have the latest version of [VS Code](https://code.visualstudio.com) and VS Code [Chrome Debugger Extension](https://marketplace.visualstudio.com/items?itemName=msjsdiag.debugger-for-chrome) installed.
-
-Then add the block below to your `launch.json` file and put it inside the `.vscode` folder in your app’s root directory.
-
-```json
-{
- "version": "0.2.0",
- "configurations": [
- {
- "name": "Chrome",
- "type": "chrome",
- "request": "launch",
- "url": "http://localhost:3000",
- "webRoot": "${workspaceRoot}/src",
- "sourceMapPathOverrides": {
- "webpack:///src/*": "${webRoot}/*"
- }
- }
- ]
-}
-```
-
-> Note: the URL may be different if you've made adjustments via the [HOST or PORT environment variables](#advanced-configuration).
-
-Start your app by running `npm start`, and start debugging in VS Code by pressing `F5` or by clicking the green debug icon. You can now write code, set breakpoints, make changes to the code, and debug your newly modified code—all from your editor.
-
-Having problems with VS Code Debugging? Please see their [troubleshooting guide](https://github.com/Microsoft/vscode-chrome-debug/blob/master/README.md#troubleshooting).
-
-### WebStorm
-
-You would need to have [WebStorm](https://www.jetbrains.com/webstorm/) and [JetBrains IDE Support](https://chrome.google.com/webstore/detail/jetbrains-ide-support/hmhgeddbohgjknpmjagkdomcpobmllji) Chrome extension installed.
-
-In the WebStorm menu `Run` select `Edit Configurations...`. Then click `+` and select `JavaScript Debug`. Paste `http://localhost:3000` into the URL field and save the configuration.
-
-> Note: the URL may be different if you've made adjustments via the [HOST or PORT environment variables](#advanced-configuration).
-
-Start your app by running `npm start`, then press `^D` on macOS or `F9` on Windows and Linux or click the green debug icon to start debugging in WebStorm.
-
-The same way you can debug your application in IntelliJ IDEA Ultimate, PhpStorm, PyCharm Pro, and RubyMine.
-
-## Formatting Code Automatically
-
-Prettier is an opinionated code formatter with support for JavaScript, CSS and JSON. With Prettier you can format the code you write automatically to ensure a code style within your project. See the [Prettier's GitHub page](https://github.com/prettier/prettier) for more information, and look at this [page to see it in action](https://prettier.github.io/prettier/).
-
-To format our code whenever we make a commit in git, we need to install the following dependencies:
-
-```sh
-npm install --save husky lint-staged prettier
-```
-
-Alternatively you may use `yarn`:
-
-```sh
-yarn add husky lint-staged prettier
-```
-
-- `husky` makes it easy to use githooks as if they are npm scripts.
-- `lint-staged` allows us to run scripts on staged files in git. See this [blog post about lint-staged to learn more about it](https://medium.com/@okonetchnikov/make-linting-great-again-f3890e1ad6b8).
-- `prettier` is the JavaScript formatter we will run before commits.
-
-Now we can make sure every file is formatted correctly by adding a few lines to the `package.json` in the project root.
-
-Add the following field to the `package.json` section:
-
-```diff
-+ "husky": {
-+ "hooks": {
-+ "pre-commit": "lint-staged"
-+ }
-+ }
-```
-
-Next we add a 'lint-staged' field to the `package.json`, for example:
-
-```diff
- "dependencies": {
- // ...
- },
-+ "lint-staged": {
-+ "src/**/*.{js,jsx,json,css}": [
-+ "prettier --single-quote --write",
-+ "git add"
-+ ]
-+ },
- "scripts": {
-```
-
-Now, whenever you make a commit, Prettier will format the changed files automatically. You can also run `./node_modules/.bin/prettier --single-quote --write "src/**/*.{js,jsx}"` to format your entire project for the first time.
-
-Next you might want to integrate Prettier in your favorite editor. Read the section on [Editor Integration](https://prettier.io/docs/en/editors.html) on the Prettier GitHub page.
-
-## Changing the Page ``
-
-You can find the source HTML file in the `public` folder of the generated project. You may edit the `` tag in it to change the title from “React App” to anything else.
-
-Note that normally you wouldn’t edit files in the `public` folder very often. For example, [adding a stylesheet](#adding-a-stylesheet) is done without touching the HTML.
-
-If you need to dynamically update the page title based on the content, you can use the browser [`document.title`](https://developer.mozilla.org/en-US/docs/Web/API/Document/title) API. For more complex scenarios when you want to change the title from React components, you can use [React Helmet](https://github.com/nfl/react-helmet), a third party library.
-
-If you use a custom server for your app in production and want to modify the title before it gets sent to the browser, you can follow advice in [this section](#generating-dynamic-meta-tags-on-the-server). Alternatively, you can pre-build each page as a static HTML file which then loads the JavaScript bundle, which is covered [here](#pre-rendering-into-static-html-files).
-
-## Installing a Dependency
-
-The generated project includes React and ReactDOM as dependencies. It also includes a set of scripts used by Create React App as a development dependency. You may install other dependencies (for example, React Router) with `npm`:
-
-```sh
-npm install --save react-router-dom
-```
-
-Alternatively you may use `yarn`:
-
-```sh
-yarn add react-router-dom
-```
-
-This works for any library, not just `react-router-dom`.
-
-## Importing a Component
-
-This project setup supports ES6 modules thanks to Webpack.
-While you can still use `require()` and `module.exports`, we encourage you to use [`import` and `export`](http://exploringjs.com/es6/ch_modules.html) instead.
-
-For example:
-
-### `Button.js`
-
-```js
-import React, { Component } from 'react';
-
-class Button extends Component {
- render() {
- // ...
- }
-}
-
-export default Button; // Don’t forget to use export default!
-```
-
-### `DangerButton.js`
-
-```js
-import React, { Component } from 'react';
-import Button from './Button'; // Import a component from another file
-
-class DangerButton extends Component {
- render() {
- return ;
- }
-}
-
-export default DangerButton;
-```
-
-Be aware of the [difference between default and named exports](http://stackoverflow.com/questions/36795819/react-native-es-6-when-should-i-use-curly-braces-for-import/36796281#36796281). It is a common source of mistakes.
-
-We suggest that you stick to using default imports and exports when a module only exports a single thing (for example, a component). That’s what you get when you use `export default Button` and `import Button from './Button'`.
-
-Named exports are useful for utility modules that export several functions. A module may have at most one default export and as many named exports as you like.

-## Code Splitting
-
-Instead of downloading the entire app before users can use it, code splitting allows you to split your code into small chunks which you can then load on demand.
-
-This project setup supports code splitting via [dynamic `import()`](http://2ality.com/2017/01/import-operator.html#loading-code-on-demand). Its [proposal](https://github.com/tc39/proposal-dynamic-import) is in stage 3. The `import()` function-like form takes the module name as an argument and returns a [`Promise`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) which always resolves to the namespace object of the module.
-
-Here is an example:
-
-### `moduleA.js`
-
-```js
-const moduleA = 'Hello';
-
-export { moduleA };
-```
-
-### `App.js`
-
-```js
-import React, { Component } from 'react';
-
-class App extends Component {
- handleClick = () => {
- import('./moduleA')
- .then(({ moduleA }) => {
- // Use moduleA
- })
- .catch((err) => {
- // Handle failure
- });
- };
-
- render() {
- return (
-
-
-
- );
- }
-}
-
-export default App;
-```
-
-This will make `moduleA.js` and all its unique dependencies as a separate chunk that only loads after the user clicks the 'Load' button.
-
-You can also use it with `async` / `await` syntax if you prefer it.
-
-### With React Router
-
-If you are using React Router check out [this tutorial](http://serverless-stack.com/chapters/code-splitting-in-create-react-app.html) on how to use code splitting with it. You can find the companion GitHub repository [here](https://github.com/AnomalyInnovations/serverless-stack-demo-client/tree/code-splitting-in-create-react-app).
-
-Also check out the [Code Splitting](https://reactjs.org/docs/code-splitting.html) section in React documentation.
-
-## Adding a Stylesheet
-
-This project setup uses [Webpack](https://webpack.js.org/) for handling all assets. Webpack offers a custom way of “extending” the concept of `import` beyond JavaScript. To express that a JavaScript file depends on a CSS file, you need to **import the CSS from the JavaScript file**:
-
-### `Button.css`
-
-```css
-.Button {
- padding: 20px;
-}
-```
-
-### `Button.js`
-
-```js
-import React, { Component } from 'react';
-import './Button.css'; // Tell Webpack that Button.js uses these styles
-
-class Button extends Component {
- render() {
- // You can use them as regular CSS styles
- return ;
- }
-}
-```
-
-**This is not required for React** but many people find this feature convenient. You can read about the benefits of this approach [here](https://medium.com/seek-blog/block-element-modifying-your-javascript-components-d7f99fcab52b). However you should be aware that this makes your code less portable to other build tools and environments than Webpack.
-
-In development, expressing dependencies this way allows your styles to be reloaded on the fly as you edit them. In production, all CSS files will be concatenated into a single minified `.css` file in the build output.
-
-If you are concerned about using Webpack-specific semantics, you can put all your CSS right into `src/index.css`. It would still be imported from `src/index.js`, but you could always remove that import if you later migrate to a different build tool.
-
-## Adding a CSS Modules Stylesheet
-
-> Note: this feature is available with `react-scripts@2.0.0` and higher.
-
-This project supports [CSS Modules](https://github.com/css-modules/css-modules) alongside regular stylesheets using the `[name].module.css` file naming convention. CSS Modules allows the scoping of CSS by automatically creating a unique classname of the format `[filename]\_[classname]\_\_[hash]`.
-
-> **Tip:** Should you want to preprocess a stylesheet with Sass then make sure to [follow the installation instructions](#adding-a-sass-stylesheet) and then change the stylesheet file extension as follows: `[name].module.scss` or `[name].module.sass`.
-
-CSS Modules let you use the same CSS class name in different files without worrying about naming clashes. Learn more about CSS Modules [here](https://css-tricks.com/css-modules-part-1-need/).
-
-### `Button.module.css`
-
-```css
-.error {
- background-color: red;
-}
-```
-
-### `another-stylesheet.css`
-
-```css
-.error {
- color: red;
-}
-```
-
-### `Button.js`
-
-```js
-import React, { Component } from 'react';
-import styles from './Button.module.css'; // Import css modules stylesheet as styles
-import './another-stylesheet.css'; // Import regular stylesheet
-
-class Button extends Component {
- render() {
- // reference as a js object
- return ;
- }
-}
-```
-
-### Result
-
-No clashes from other `.error` class names
-
-```html
