What the model said
I made one change to `0.html`: I added `search` to the block-spacing rule at `0.html:51`, so a `<search>` element gets the same bottom margin as `form`. I didn't open the page in a browser. I reviewed the rest of the stylesheet and markup and found nothing else that was clearly wrong, so I left it alone. ## Judgement calls I left untouched - **Tables:** `display: block` on `table` gives you horizontal scrolling without a wrapper, but it can drop table semantics for some screen readers. The alternative is a scrollable wrapper `div`, which costs extra markup. - **Line length:** `40rem` in `system-ui` runs about 85 characters per line. Something like `65ch` would be closer to the usual 45–75 range. - **Small headings:** `h4`, `h5` and `h6` all render at 1rem bold, so they look identical. - **Loose lists:** the `li > :last-child` margin reset means list items that contain paragraphs have no gap between items. - **Print:** closed `<details>` print with their content visible but still show the closed marker. ## Content The title and `h1` are both the placeholder "0", and there is no `<meta name="description">`. I didn't invent content for either. If "improve" meant something different — visual design, real content, or a component — tell me which and I'll do that.
