Default MDX Admonition component — the render target for the GitHub-style
> [!NOTE] blockquote-alert syntax (the transpiler remark plugin, R3-152,
compiles that syntax to <Admonition type="note">…</Admonition>).
It is registered in DEFAULT_MDX_COMPONENTS so an admonition renders
even in a plain-markdown repo that never calls boot({ mdxComponents }) — the
MDX missing-reference guard never fires (MARKDOWN_SYNTAX_SPEC §11.2 phantom
defaults). The markup is semantic and accessible; styling is intentionally
minimal — an app supplies CSS targeting the ir-admonition* classes, or
overrides this component via boot({ mdxComponents: { Admonition } })
(MARKDOWN_SYNTAX_SPEC §12.3).
