What the model said

I added some basic improvements to `0.html`, but I couldn't do much more because the page has no content yet.

- **Page setup:** added an empty `description` tag for search engines, `color-scheme` so the page supports dark mode, and a placeholder favicon so the browser doesn't request a missing `/favicon.ico`.
- **Base styles:** a readable column width, a system font, comfortable line spacing, `box-sizing`, and images that shrink to fit the screen.
- **Structure:** a `<main>` element to hold the page content, which also helps screen readers.

The title is still "0". Tell me what the page is for (a landing page, a portfolio, a form, etc.) and I can fill in the title, description and content.
