Nested Cross-Validation in Python: Get Honest Scores After Tuning

Nested cross-validation: how to get an honest estimate of a tuned model’s performance and avoid optimistic bias.
Follow a reproducible scikit-learn pipeline (Pipeline, StandardScaler, LogisticRegression, GridSearchCV, StratifiedKFold) with NumPy to compare naive vs. nested scores and report accuracy with a confidence margin.
