Where?

300 to 400 users is still quite a lot if they are all online at the same time.

There's one thing you can guarantee - new versions of *any* software never requre *fewer* resources.

You don't give us any clues about the resources available in your shared hosting but shared hosting is rarely adequate to run a production Moodle site.

You don't.

The only way you will get a SCORM package is to build the learning module in a package that provides SCORM output. Nothing to do with Moodle. You can, of course, then "play" it in Moodle.

As you seem to have identified, it's probably a DNS issue.

Is this *just* Moodle? If so, what's special about Moodle, compared to everything else? Where is Moodle hosted?

I'm not familiar with figma (I just Googled it).

Moodle has a "look and feel" all of its own defined by the functionality it has. You can customise the look to a large extent using a custom theme but it's still going to look like Moodle. The chances are that if somebody has created a design without any knowledge of Moodle, you will have a VERY hard time implementing it.
