Subject: [PATCH 1/3] Name the share button and the page heading on small
 screens

On small screens the share button shows only an icon, and its text was
`display: none`, so the button had no accessible name. The text is now
visually hidden in place of removed.

The `h1` held only a link that is hidden on small screens, so the
heading was empty there. It now has visually hidden text.

Subject: [PATCH 2/3] Add llms.txt

No file existed, so the single page app fallback answered `/llms.txt`
with `index.html`.

+# Limber
+
+> Limber is a playground and REPL that runs in the browser. It compiles and renders Ember (gjs, gts, hbs), Svelte, Vue, React (jsx), Mermaid, and markdown with live code fences. The document lives in the URL, so a link shares the whole program.
+
+The app has no server side. All compilation happens in the browser of the visitor.
+
+## Use
+
+- [Editor](https://limber.glimdown.com/edit): the playground. The `format` query parameter selects the language, and `t` (plain text) or `c` (compressed text) holds the document.
+- [Output only](https://limber.glimdown.com/output): renders a document with no editor, for an iframe.
+

Subject: [PATCH 3/3] Name the share button with aria-label

The span goes back to `hidden` on small screens, and the button gets
`aria-label="Share"`. The template comments are gone too.
