Patrol Suite SpeedLimits.csv

Format:
street,zone,limit
or:
street,limit

Zone is optional. Patrol Suite checks the current road only: exact street + zone, then street-only, then fallback road-type rules.
Cross streets are intentionally ignored so overpasses, underpasses, and intersections do not make the displayed limit jump.
This file powers the SimpleHUD-style speed-limit sign and patrol HUD road readout without any OpenIV map installer.
