Supports scenario-based corridor planning with\nbudget-constrained optimization, optional impassable areas,\npackaged parity fixtures, and comparative PRE/POST connectivity\nmetrics. The package exposes TerraLink's structural,\nmovement-oriented, and species-oriented strategy set in a\nscriptable R workflow that stays aligned with the QGIS plugin\nwhile avoiding a desktop GIS dependency.
