+# Repository Technical Context
+
+This repository is a monorepo that uses Lit for building web components and no other frontend frameworks unless otherwise specified.
+
+## Coding Patterns
+
+- Uses standard ESM imports
+- TypeScript imports end with `.js` extension
+- Decorators are used, but other TypeScript features that are not standard JavaScript are avoided
+- Focuses on native, modern browser features, including custom elements, Shadow DOM, and css custom properties.
+
+## Build System
+
+- Google Wireit orchestrates npm scripts
+- Wireit script configurations:
+  - Declare file inputs and outputs
+  - Specify script dependencies
+  - Cache build artifacts in `.wireit` directories
+  - Prepending `WIREIT_LOGGER=simple npm run <command>` outputs the full logs to the console
