Why not code in assembly?
I kid but any reason you can think of applies to app development too.
1. Good abstractions decrease verbosity and improve comprehension
2. Raw HTML/CSS/JS are out of distribution just like assembly (no one builds apps like this)
3. Humans need to understand and audit it
4. You'll waste time and tokens reinventing wheels
This inuitively makes sense. LLMs mimic human behavior and thought, so for all the reasons you'd get lost in a pile of web spaghetti or x86, so would an LLM.

Plenty of people build apps with vanilla CSS and JS (and HTML is just HTML). It's a really nice way to work.
Here are a few links to get you started.

Plenty of people, but how many companies?
Plenty of people bake bread from scratch without a mixer, but few (if any) bakeries do.
Companies are comprised of people.
It's also a good opportunity to use the platform, to get layering naturally.

> If a gen-UI pre-viewer can load standard JS modules, it can load Lit components. No custom Angular, Vue, or Svelte toolchain integration needed.
