How to prevent any sanity recovery from any sources except eating specfic food, killing shadows, during full moon and being in lunar boimes?

I've just started making my first mod ever and got some troubles...

Blast, that's a lot of restrictions! Well thankfully it's doable. And welcome to the forums.

Specific food
I recall there being a custom stats mod fn that you can use to determine what goes in your belly and gives how much stats. It simply involves the food prefab and more things you can determine from.

Killing Shadows
This already works fine given how shadows simply just pull your sanity up when killed.

Full Moons
Maybe a WatchWorldState. Possibly not too hard either? Depends on how you want the full moon to interact.

Lunacy biomes
Also depends. Do you simply want the biome to do its usual daytime passive regen of +0.625? That's already given if so.

I'll get onto this later if I have the time. Do specify or clarify things if you wish to.
