Spaceship Integrity

How does spaceship integrity stress work?
You have an integrity stress limit based on your tech. With just spaceship tech you have a limit of 200. Spaceship Integrity research increases it by 100 per tech up to a max 1000. Factory Spaceship research increases it by 500 per tech with no limit.

Integrity stress is calculated in 2 parts, whichever value is higher determines the actual stress.

Part A is based the size and structure of the ship: Each spaceship tile with a spaceship wall takes 0.5 integrity, each spaceship tile without a wall takes 1 integrity.

Part B is based on cargo capacity: Each item slot of a chest or similar container takes 0.5 integrity, each 2k of fluid capacity takes 1 integrity (except booster tanks which are 1 integrity per 4k).

Example:

The ship has 60 tiles with walls, and 160 tiles without walls. The integrity stress is 30 + 160 = 190 from size.

The ship has 10 containers with 48 slots each. The integrity stress is 10 * 48 / 2 = 240 from cargo.

The total stress is 240 because 240 is higher than 190.

If 2 containers are removed for a total of 8 containers the stress would drop to 192.

If 2 more containers are removed for a total of 6 containers the stress from containers would drop to 144, but the total stress would be 190 from the spaceship size.
