Consolidates everything bulky (tracking DBs, targets, metadata
spreadsheet) under a single DATA_VOLUME root outside the ownCloud-synced
repo. Notebooks now use a visible DATA_DIR = Path(...) idiom rather than
walking up the filesystem with PROJECT_ROOT.parent — easier for students
with no Python background to follow.

Four guided notebooks under notebooks/getting_started/ aimed at someone
new to Python and data science. The series progresses: project orientation
→ Python/pandas crash course → exploring one tracking DB → first
trained-vs-naive comparison using load_roi_data + Mann-Whitney U.
Each notebook leans heavily on markdown explanations, includes exercises
with empty cells, and links out to canonical references (JupyterLab,
official Python tutorial, pandas 10-min guide, Wikipedia for stats
concepts).
