 * Error toast, pinned to the top-right of the viewport. Renders nothing when
 * there is no error, so it clears itself once the code compiles again.
 *
 * Dismissal is tracked by message, not by a boolean: a *different* error after
 * a dismiss shows the toast again, while re-renders of the same error stay
 * hidden. No effect needed to reset it.
 *
 * Two layout constraints worth preserving if you restyle this:
 *
 * 1. `#react-code-error` must never itself be `position: fixed`. Downstream
 *    consumers poll it with
 *      err.offsetParent !== null && err.textContent.trim().length > 0
 *    to detect "this code cannot render" without waiting out a full timeout,
 *    and `offsetParent` is null for fixed-position elements. The container may
 *    be fixed — offsetParent then resolves to it — but the id must stay on a
 *    statically positioned descendant.
 *
 * 2. Incoming props (including `id`) are spread onto that inner `<pre>`, whose
 *    textContent is only the message. The warning glyph and dismiss button sit
 *    outside it so scraped error text stays clean.
