Purchase Movie Theater Concessions

I saw that there was a mod that allowed you to buy recipes, and one that allowed you to randomly obtain them from a vending machine, but none that let you directly purchase them, so I made one myself!

I want to point out that I wanted this so badly that this is actually the reason I learned modding.

What this mod does:
Creates a new shop in the Movie Theater that allows you to purchase for yourself one of each concession item every time you go — at a slight markup, of course. This should work in both a Community Center game and a Joja Member game.

Also, every Friday and Sunday, the Traveling Merchant will randomly offer one concession item for sale at a fixed price.

JojaCorn is not available for purchase at the Movie Theater in a Community Center game, only in a Joja Member game. However, the Traveling Merchant may still have it rotate into her stock.

Concession items may be eaten to restore Energy and Health, and some even give temporary stat boosts! (ex. the Stardrop Sorbet will give +5 Luck for ~2 minutes.)

Concession items can be gifted to villagers; all of them have the appropriate Loves, Likes, and Dislikes. None are Neutrals or Hates. Current NPCs supported are:
-Vanilla
-SVE

This mod hasn't been tested in the Joja Member route, however, the appropriate edits have been made; if anyone in the Joja Member route notices any bugs/issues, upload a SMAPI log and let me know!

Compatibilities:
Theoretically, this mod should be compatible with any mod that doesn't edit those specific tiles in the Movie Theater. If that's not the case, please let me know. I'm still new to modding and this was the most complicated mod I've made so far – I can't guarantee I'll be able to fix it if something breaks.

While Json Assets should not complain about duplicate items as of V2.0.0, the following items have configurable names for convenience and compatibility:
-Chocolate Popcorn <-> Choco Popcorn
-Cotton Candy <-> Candy Floss
-Ice Cream Sandwich <-> Vanilla Cream Sandwich
-Jasmine Tea <-> Blossom Tea
-Joja Cola <-> Joja Cola XL
-Popcorn <-> Classic Popcorn
-Truffle Popcorn <-> Gourmet Popcorn

Only configure the items when you first start the game up. If you configure at any point after loading a save file (even if you go back to the title screen), you MUST exit the game as SMAPI will complain. Your configurations will function normally when you next start the game up.

Likewise, this mod hasn't been tested with SVE, but there doesn't seem to be any reason for incompatibilities; again, let me know if there are.

If a custom NPC has concession Loves/Likes/Dislikes, and you want them to be compatible, let me know!
