\multicolumn{8}{p{0.96\textwidth}}{\footnotesize Notes: ``manual'' means at least one endpoint requires manual coordinate validation. Population is WorldPop 2020 within the 500 m total buffer. Ratio is $(H+1)/(B+1)$. Stability A/E reports fixed-seed top-six selection frequency for absolute exposure and service-to-exposure efficiency.} \\
