+; Sol Skies world map (src/core/world_map.h; Sol-Skies-Client docs/rem/large-world-scale-plan.md 4.7).
+; rem-server.ini: [World] Map = <path of this file>. Multiplayer only - without it every system stands at
+; the origin as before (single player, the classic systems). The system inis are never changed: each
+; system is placed as a whole at its universe.ini map position x the region's grid.
+;
+; Grid 400 km: the tightest neighbours on the REM universe map (Rh01 153 km and Rh03 133 km, one field
+; apart) need 306 km, so every pair of systems keeps at least ~94 km of empty space between their
+; outermost objects. The map is 16 x 16 fields = 6,400 km.
+
+; The Sirius sector: every Freelancer system, 8.6 light years from Sol along +x. The region's origin is
+; the map's (0, 0) field, so that the map's centre (8, 8) lies at x = 81362082064195072 m, z = 0.

+; How Sol comes in at true scale (once its systems exist - mod data, not here yet): each planet's
+; neighbourhood is a system of its own (a classic FL-sized ini: its station, moons, lanes), placed at its
+; true distance from the Sun with an exact [Place] origin (metres, relative to the region). The systems
+; keep small coordinates, so client physics stays exact; between them the jump drive's FTL jump carries the
+; ship (no jump connection needed: [Native.JumpDrive] Interstellar, the tunnel lasts the distance at
+; FtlLightYearsPerMinute). Sirius <-> Sol (8.6 light years) is the same FTL jump.
