# ships.toml
#
# First real-content iteration: ship ids and layout grids are the designed
# content; stats, materials, and production times are placeholders until the
# recipe and balancing passes.
#
# Unlock progression is mostly disabled (unlock_at_station_level = -1) pending
# the balancing pass. The capital hulls are the exception: battleship is gated
# to station level 1, and dreadnought (level 2) requires battleship to be
# unlocked first (unlock_requires) — a demonstration of the prerequisite chain.
#
# Size classes:
#   xs  drone                      1 cell — exactly one 1x1 module
#   s   frigate, destroyer         no 2x2 area anywhere: only 1x1/1x2/1x3/L modules fit
#   m   cruiser, battlecruiser     2x2 areas (m guns, drone bays) but no 3x3 area
#   l   battleship                 four m guns, or exactly one 3x3 l gun at heavy
#                                  opportunity cost
#   xl  dreadnought, carrier       dreadnought fits three l guns but no drone
#                                  hangar; carrier fits one drone hangar (2x6)
#                                  but no l gun (its deck rows are broken up
#                                  by elevator shafts)
