% “data preprocessing” → du gjør faktisk HAR → CSV-transformasjon
% “EDA” → du lager konkrete Power BI-visualiseringer
% “data pipeline” → du automatiserer hele workflowen
% “data reliability” → du standardiserer browser/proxy conditions
% “data collection methodology” → du dokumenterer Playwright/Tor-oppsettet
