What happens after Continue
Your selection travels as preset IDs and the server builds the runtime from them.
Continue opens Generate my site with your description and the IDs of the presets you picked already in the prompt box. That ID sentence is not a hint the model may ignore: the generation route parses it, checks every ID against this catalog, and binds the result to the runtime it declares — so a 3D pick keeps a real WebGL scene and a 2D pick stays CSS and canvas motion.
A selection counts as 3D only when one of the presets in it actually declares a supported WebGL renderer or 3D model — never because a pack, family or capability name mentions 3D. That is why a template pack can lock a real WebGL scene: the selector names the preset responsible, and the generator page repeats the same answer for the same selection.
The generator page shows which presets are still attached, and warns you if an edit removed them. If you skip the selector entirely, the generator picks a deterministic mix from the same pool instead, so one prompt still produces 3D, parallax, scroll, hover and text animation decisions.
Presets only decide how a page looks and moves, so add the store description too — that is the part that makes the generated copy about your business rather than a generic demo. Nothing here changes anything on its own: no account, no draft and no generation happens until you submit the prompt on the generator page.

Generated pages still open in Theme Designer.
Presets become normal editable sections, layers, images, timing values, hover behavior and motion tokens inside the store editor.
