Description: Provides a unified and reproducible framework for statistical
    inference of spatiotemporal trends in gridded environmental data. The
    framework addresses the interconnected challenges of serial correlation,
    spatial dependence and multiple testing that commonly arise when analysing
    gridded environmental time series. Its core methods support
    serial-correlation treatment through trend-preserving prewhitening,
    pixel-wise and spatially explicit trend inference, slope estimation and
    multiple-testing correction. These methods may be applied independently or
    integrated within configurable analytical workflows. Dedicated workflows
    are also provided to reproduce methodologies published in the scientific
    literature: Gutiérrez-Hernández and García (2025)
    <doi:10.1016/j.rsase.2024.101377> for the True Significant Trends
    workflow, Gutiérrez-Hernández and García (2024)
    <doi:10.3390/rs16203886> for the Robust Trend Analysis workflow, and
    Gutiérrez-Hernández and García (2025) <doi:10.3390/math13223630> for
    the adaptive false discovery rate procedure. Supporting utilities
    facilitate raster data import and
    inspection, anomaly calculation, spatial autocorrelation diagnostics,
    simulation studies, benchmarking, visualisation, mapping, and reporting.
