What the model said

`0.html` was already a solid base stylesheet, so I made a few targeted fixes rather than reworking it. Nothing was rendered in a browser to check them.

## Changes

- **SVGs without a `viewBox`**: `block-size: auto` now applies to `svg[viewBox]` only. Before, an `<svg width="24" height="24">` with no `viewBox` had its height attribute overridden and would render 150px tall.
- **Fieldsets**: added `min-inline-size: 0` so a fieldset with wide content can't overflow on narrow screens. I also zeroed its inline margin, gave it the same 1rem bottom spacing as other blocks, and added it to the print `break-inside: avoid` list.
- **Textareas**: `resize: vertical`, so they can't be dragged wider than the column.
- **Horizontal rules**: `hr` gets `margin-block: 2rem`, matching the spacing above headings.

## Left alone

- **Title and `<h1>`**: both are still the placeholder "0", and there is no `<meta name="description">`. Those need real content from you.
- **Scrollable `pre` and `table`**: they can't be scrolled by keyboard unless each element gets `tabindex="0"` in the markup; CSS can't fix that.
