+-- Selectable scenarios. The engine loads every entry of the global `Maps` array
+-- and the Dev panel ("Map" section) switches between them at runtime; switching
+-- tears the world down and rebuilds it from the chosen entry. Maps[1] is the
+-- one the game starts on.
+--
+-- Each map is self-contained:
+--   name, description   shown in the Dev panel
+--   ground_level        height of the ground plane. Terrain is still a flat
+--                       half-plane, so this moves the ground up/down but cannot
+--                       change its SHAPE (real terrain is M6).
+--   deposits            { {x, y}, ... }  mines only produce while on one
+--   devices             { {type=, x=, y=, team=}, ... }  team 0 = player
+--   weapons             { {type=, x=, y=}, ... }  the player's starting guns
+--   structures          { {name=, beams={ {x1,y1,x2,y2,material}, ... }}, ... }
+--
+-- Building rules the beams must respect (see data/materials.lua):
+--   * a beam should be <= 3 units (wood/armour/bg-brace max_length); prebuilt
+--     beams are welded raw and are NOT auto-subdivided
+--   * TRIANGULATE. An un-triangulated strut snaps once it rotates ~30 degrees,
+--     so every bay wants a diagonal or the fort folds up on the first hit
+--   * an endpoint at y == ground_level becomes a pinned foundation; keep other
+--     nodes clear of the ground+0.3 band so they don't pin by accident
+
