Can we have a custom HTML homepage and have the other pages be Kirby-powered?

Hi there,
I wanted to have complete HTML/CSS control over my homepage for my site, but have Kirby give me a hand for uploading projects, blog posts, etc.
Is there a way to do this? The Kirby pack comes with its own index.php, so I’m not sure how much I’m able to manipulate.
Yes, I know this means the rest of the site will most likely look a little different on other pages.
The templates from the scratch process are difficult and I would love to visit it again in the future, but I’m in a bit of a time crunch.

Hey, why can’t you put your HTML into the home.php template, which is responsible for rendering the home page, not the index.php (even all hard-coded HTML/text if need be), then there is no need for a mixture.

Thanks for your help! Don’t know why I didn’t think of that earlier, makes perfect sense.
