Note: This reference table documents components 0-95 from the Minecraft Wiki documentation:
https://minecraft.wiki/w/Java_Edition_protocol/Slot_data#Structured_components

Important: The code analysis above shows that later Minecraft versions (1.21.11+) contain
additional component IDs beyond those documented on the wiki. Refer to the extracted comparison
tables for versions 1.21.9, 1.21.10, and 1.21.11 above to see the actual component mappings
for each version, which includes these additional values.
