Files to be created

From 1.21 the folder is function (singular) instead of functions — the tool switches based on your version.
A wrong pack_format does not break the pack; the game just marks it incompatible and still loads it.
load runs once when the world loads; tick runs every game tick (1/20 s) and can easily lag the server.
Paths inside the ZIP must follow data/<namespace>/... or the game will not find them.
