-- 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
