Ular Kimsanov a06fdfe26e docs(catalog): put each item page's title, description and Docs text in the server HTML (#6711)
* docs(catalog): put each item page's title, description and Docs text in the server HTML

Mintlify renders snippet components in the browser only, so everything inside
CatalogDetail (title, standfirst, the Docs tab) was missing from the HTML search
engines read: 448 catalog pages served Googlebot no body text. The generator now
writes the H1 and standfirst as page markup above the component and the Docs tab
as page markup after it, shown with that tab (docs/custom.css). The component no
longer draws its own title. Pages patched structurally only; registry drift on 14
pages is left for a regeneration of its own.

* docs(catalog): keep the title's top spacing the component gave it

* fix(docs): catalog titles and descriptions keep markdown markers literal

MDX reads text inside the static <h1> and <p> as inline markdown, so @_blue_sweater_
rendered as italic blue_sweater. mdxText now writes backslash, backtick, * _ [ ] ~ as
character references too, with a unit test; the four affected pages are re-escaped.

## Add it to your video
It runs for 8 seconds at 1920×1080. Paste this into your composition:
```html index.html
<div
data-composition-id="thread-message-stack"
data-composition-src="compositions/thread-message-stack.html"
data-start="0"
data-duration="8"
data-track-index="1"
data-width="1920"
data-height="1080"
></div>
```
Move it in time with `data-start`. Put it on a different timeline row with
`data-track-index`. See [data attributes](/concepts/data-attributes) for the rest.
{/* hf:generated-footer */}
Tagged `social` `conversation` `messages`.
