Integration of a warship ammunition production line

Add a naval ammo production line for warships. Shells are required before departure and consumed only when enemies are encountered.
Tier 1 Shell: Copper + Explosive T1 (Toluene + Sulfuric Acid)
Tier 2 Shell: Steel + Explosive T2 (Explosive T1 + Ethanol + Ammonia)
Tier 3 Shell: Hardened Steel + Explosive T3 (Explosive T2 + Liquid Nitrogen)
Each shell tier could be tied to late-game ship upgrades. No shell consumption when no enemies are present.
Recipes are intentionally simplified to respect age ratings, platform policy, and legal concerns while adding meaningful logistics and depth to late-game combat systems.
This feature would enhance immersion and realism by making the warship more than a simple button, turning each deployment into a meaningful logistical challenge.
