Description: Tools for road-constrained, least-cost pedestrian evacuation modeling.
    The package provides reusable functions for preparing hazard zones, generating
    road-based evacuation origin points, identifying escape/safety points, creating
    slope-based conductance surfaces, calculating least-cost distance to safety,
    and converting distance outputs into evacuation-time polygons. It is designed
    to support workflows like tsunami evacuation modeling while remaining
    adaptable to other regions and hazards. Tsunami-specific helpers support separate
    land-only hazard zones, water-combined escape zones, road-aware escape
    boundaries, and study-area inset cropping for quality assurance and quality
    control. Methods build on Cordero et al. (2025) <doi:10.1007/s44367-025-00018-y>,
    Lewis (2021) <doi:10.1007/s10816-021-09522-w>, and Joseph Lewis's
    'leastcostpath' package (2023) <https://CRAN.R-project.org/package=leastcostpath>.
