Help me start contributing to this project using ONBOARDING.md from the DataProof Onboarding Kit.

Mode: open-source contributor
Project: use the repository open in this workspace
My goal: understand where I can help and prepare one realistic first contribution
Experience: use my attached CV or the summary I provide
Preferred language: use the language of my request

Read the onboarding instructions and the project's contributor guidance first. Read my CV only to identify transferable skills and choose the right level of task. Do not score me, repeat personal details or decide whether the project should accept me.

Show me:
1. which one or two project areas best match my experience and why;
2. what I should read first;
3. how contribution and review work in this project;
4. one primary first contribution, with scope, evidence, verification and completion criteria;
5. what I should ask a maintainer to confirm before I begin.

Use a real open issue only if you actually inspect it and it appears unclaimed. Otherwise propose a task without claiming it is assigned. Write onboarding.md, onboarding.html and notes.md outside the repository. Do not modify code, claim an issue, install dependencies or contact maintainers.
