…kdown Regex-stripping raw Markdown/MDX source couldn't reliably handle the site's remark/rehype pipeline (math, admonitions, link cards, autolink headings, etc). Astro's content loader already stores the fully rendered HTML for each entry (`entry.rendered.html`), so strip that instead, which only requires handling real HTML tags/entities.

Replace the manual HTML-tag-stripping regex with hast-util-from-html (parse5-backed HTML parser), hast-util-to-text (innerText-like plain text extraction), and unist-util-remove (drop the decorative "#" heading-anchor links before extracting text) — all official packages from the same unified/syntax-tree collective that already powers this site's Markdown pipeline.

Summary
src/lib/excerpt.ts, which strips common Markdown/MDX syntax (code fences, headings, links, emphasis, etc.) from an article's raw body and returns a short plain-text excerpt.description/og:descriptionmeta tags, instead of always falling back to the site-wide description.description→ excerpt from body → site description (unchanged behavior for body-less/redirect articles, which still show the site description).Test plan
