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
