# Data-driven enemy stats and appearance, mirroring VesselDefinition's role

# Ship.gd does, so behaviour (pursuit, ranged fire, ...) lives in capability
# components rather than in a type switch here.

# Interior detail drawn on top of the hull, as consecutive PAIRS of points
# (a, b, c, d -> segments a-b and c-d). Every enemy used to be a single flat
# outline, which left the artillery and the turret spawner as the same
# octagon at two sizes - the silhouette carried no information about what a
# thing did. Kept as DATA rather than a per-type draw branch, for the same
# reason hull_points is: adding an enemy must not mean editing Enemy.gd.

# #82: this enemy is destroyed by the impact when it reaches a player vessel,
