nav: nav_tiles_keep_near - a file-backed mesh's tiles kept by a distance the game answers (its players' zones, ludic.zones' zones_nearest): in within pad of it, out only past pad + hyst; the tile counters in resident_count.ludic

Browse source 
For loading the world by each player's fog rather than a fixed 900 m. keep_near_test: a zone round
one corner brings in its tile, a bigger one its neighbours, an edge nudged back and forth twenty times
changes nothing, and a zone moved 2 km away lets them all go.
