Decide whether notebooks are archival artifacts or active workflows

[eneskemalergin]

Summary

The notebooks currently contain saved outputs and figures. The repository should state whether these notebooks are meant to be archival thesis artifacts or actively rerunnable workflows.

Tasks

• decide whether notebook outputs should stay in git long term
• if keeping them, label notebooks as archival artifacts
• if not, define how figures or outputs should be published instead

Acceptance criteria

• the notebook strategy is stated clearly in the repository
• users know whether rerunning the notebooks is expected

Why this matters

This affects repository size, maintenance style, and user expectations.
