Description: Provides a framework for quality-aware analysis of ground-based
    phenological data from the PEP725 Pan-European Phenology Database
    (Templ et al. (2018) <doi:10.1007/s00484-018-1512-8>;
    Templ et al. (2026) <doi:10.1111/nph.70869>) and similar observation
    networks. Implements station-level data quality grading, outlier
    detection, phenological normals (climate baselines), anomaly detection,
    elevation and latitude gradient estimation with robust regression,
    spatial synchrony quantification, partial least squares (PLS) regression
    for identifying temperature-sensitive periods, and sequential
    Mann-Kendall trend analysis. Supports data import from PEP725 files,
    conversion of user-supplied data, and downloadable synthetic datasets
    for teaching without barriers of registration.
    All analysis outputs provide 'print', 'summary', and
    'plot' methods. Interactive spatial visualization is available via
    'leaflet'.
