Hey!

Yes that is correct, I mean the HTML page loading.

“at the end of the day” is an expression, I don’t mean literally at the end of the day.

Maybe this diagram will help:

This flow only happens once, only when the page is first loaded.

After this initial transaction, internet is no longer required (so you are correct, if you keep your page open everything should be fine).
