The easiest way is probably to ignore the laptop, use a web spidering tool to download all of the content, and upload it to a no-code HTML tool like maybe wix.com (which I haven't actually used) and make changes using that. A second option might be to ignore the laptop, use a web spidering tool, and then manually edit the HTML. That would not be very fun. If this is an actual business, yoga studio websites these days…
Surely something like this should already exist.
