Observations

• The storage layouts are formed according to the rules in https://docs.soliditylang.org/en/latest/internals/layout_in_storage.html#layout-of-state-variables-in-storage

• Structs can occupy multiple slots depending on the size required by its members.

• Fixed arrays can occupy multiple slots according to the size of the array and the type of array.
