Per the sveltekit documentation and the tutorial, it says, "You may be tempted to do this," and then it shows an example of a store value being set inside a load function on your +page.js. It goes on to say that value will be available to all users, and that has confused me.

My particular application needs are solved mosts conveniently by setting a store's value in the +layout.js file, and then dozens of small components reference that store's values instead of always having to every time I use and re-use these components.

I am just confused how setting the store value in the load function on the client side would impact all the users. It reads confusing.

Can someone explain what they mean?
Thanks.
