+## Contributor Guidelines
+- Keep changes focused and incremental; avoid drive-by refactors.
+- Follow existing Angular + TypeScript patterns and keep lint/build clean.
+- Prefer pure, testable functions for data transforms and heavy parsing.
+- Use Web Workers for CPU-heavy operations to keep the UI responsive.
+- Keep UI components accessible (labels, contrast, keyboard focus, ARIA where needed).
+- Respect privacy-by-default: no new tracking, network calls, or telemetry without explicit discussion.
+- Update docs when you add or change tools, routes, or build behavior.
+
+Before opening a PR:
+- Run `npm test` and `npm run build`.
+- Verify the affected tool in the browser (inputs, outputs, and error states).
