DramaticShapeVoxelMod/tests/mon_shots.lua

-- Driver: one overworld-battle screenshot per species, the mon fighting
-- ITSELF -- its back pic on the player's mark and its front pic on the
-- enemy's, so a single frame shows both sprites the 3D mode draws for it.
--
-- The point is a visual sweep for pic glitches (holes the paper-fill missed,
-- a silhouette cut wrong, a pin that leaves the mon floating), so every shot
-- is staged identically: same map, same cells, same beat -- the battle menu,
-- both HUD panels up. Whatever differs between two shots is the mon.
--
--   SHOT_DIR=.scratchpad/mon_shots \
--   POKEPORT_DRIVER=mods/DramaticShapeVoxelMod/tests/mon_shots.lua love .
--
-- Files land as NNN_species.png in dex order.
