Description: Provides functions to build and use hexagonal discrete
        global grids using the Icosahedral Snyder Equal Area ('ISEA')
        projection (Snyder 1992 <doi:10.3138/27H7-8K88-4882-1752>) and
        the 'H3' hierarchical hexagonal system (Uber Technologies).
        Implements the 'ISEA' discrete global grid system (Sahr, White
        and Kimerling 2003 <doi:10.1559/152304003100011090>) and the
        'Hex9' octahedral grid (Griffin 2026 <arXiv:2608.00022>).
        Includes a fast C++ core for 'ISEA' projection and aperture
        quantization, an included 'H3' v4.4.1 C library for native 'H3'
        grid operations, and 'sf'/'terra'-compatible R wrappers for
        grid generation and coordinate assignment. Output is compatible
        with 'dggridR' for interoperability.
