The Wiring Between a Theme and Your Data Is the Whole Job
A design in the catalog is a purchased theme with your account wired into it. That wiring is the work. It is also most of what separates a template you could download anywhere from a website that is actually yours.
What gets bound
Nearly everything on the page. Your name and the way it is displayed. Your headshot, and the gallery behind it. Your bio. Your credits, grouped and ordered the way you set them. Your training, skills and awards. Your press. Your contact route. Your social links, and the icon set they are drawn in. Your accent color.
Images are part of this too, and less obviously. A theme references its own images by relative path into its own folder. A design serves yours, from your account, through the image delivery network. That is why swapping designs does not mean re-uploading anything.
What happens where you have nothing
The section is not drawn. This sounds minor and it is the difference between a sparse site and a broken one.
A theme's demo has content in every slot, because it is a sales page. A real actor has gaps, and gaps change over time. So each block asks whether you have rows before it renders a heading, and a label disappears when its field is empty rather than printing a bare "Web:" with nothing after it.
The practical effect is that a half-finished profile looks deliberate. You can put up a site with a headshot, a bio and three credits, and it reads as a site with a headshot, a bio and three credits, not as a site with four empty headings.
Why designs are ported rather than just installed
A theme ships pages for whatever industry its author had in mind: a shop, an events calendar, a services grid, a pricing table. Those are not carried across, because an actor has no use for them and every page kept is a page that has to keep working.
What stays is the part worth having, which is the theme's idea of how a page should look. That is why the catalog has genuine variety rather than one layout with a color picker. More on that in how a design gets into the catalog.
You can preview any design against your own content before committing, which is the only reliable way to judge one. Browse the catalog or create a free actor website.
