Luau Formatting Tips

Use tabs for indentation, as recommended by the official Roblox Lua Style Guide that StyLua follows.
Annotate function signatures with Luau types — the formatter keeps them aligned and readable.
Prefer compound assignments (+=, -=, ..=) and string interpolation (`hello {name}`) for cleaner Luau code.
