## Summary A cleanup pass across the blog: route and feed bugs fixed, SEO basics added, smaller and lazier images, accessibility fixes, and a real README. No content or design changes beyond small fixes. ## Bug fixes - **Tag/category pages**: static params now use slugs, so pre-rendered pages match the links (before, `/tags/standard-model` was only rendered on demand and the pre-built pages said "Tag not found"). Unknown slugs now return a real 404, and there's a new not-found page. - **Recently updated**: sorts by last modification *before* taking the top 5, so older posts that were updated recently now show up. - **Atom feed**: `rel="self"` now points to `/feed.xml` (was `/feed`); `<updated>` uses the `updated` frontmatter field. - **No-JS flash**: the `no-js` → `js` class swap runs in an inline `<head>` script before first paint, not after hydration. - **Markdown links**: only internal paths go through `next/link`; `#anchors`, `mailto:` and links without an `href` no longer break. - **Invalid HTML**: images in a paragraph together with text (e.g. "**Screenshots:**" followed by images on the Projects page) produced `<p><figure>` and a hydration error. Those paragraphs are now split. - **Dates**: frontmatter dates are normalized to ISO, so `<time datetime>` values are valid. Formatting is pinned to Europe/Prague so a UTC build server can't shift a date by a day. ## SEO - `sitemap.xml` and `robots.txt` - Canonical URLs, Twitter cards and a feed link on every page, built by a shared `pageMetadata()` helper - Generated Open Graph images: a site card, and for each post its cover image or a branded title card (pre-rendered at build time) - `BlogPosting` JSON-LD on post pages ## Performance - Only the post cover and the latest-post image are preloaded (was: every image) - In-post image quality 100 → 90, plus responsive `sizes` - Screenshots downscaled to 1800px wide; `linkboard-old.png` converted to WebP (3.1 MB → 60 KB) - `CodeWrapper` is now a server component; only the copy button ships to the client - Mermaid CDN script pinned to `11.17.2` for reproducible builds ## Accessibility - Accessible names for icon-only links (share, social, mobile nav) and `aria-current` on active nav items - Copy button: uses React state instead of mutating `innerHTML`, handles clipboard errors, announces the result to screen readers, and is no longer inside an `aria-hidden` header - Code-block line numbers hidden from screen readers - Image captions: the Markdown `"title"` becomes the caption; captions that only repeat the alt text are hidden from screen readers ## Content & maintenance - **Frontmatter validation**: a missing or malformed field fails the build and names the file, instead of rendering a broken post - **`draft: true` support**: drafts only render in development - About/Projects/Setup pages share one `MarkdownPage` component; tag/category lists share `PostList` - Markdown rendering is cached, so metadata and page share one render - New README covering features, env vars, frontmatter schema, Markdown extensions and deployment - Removed unused ESLint setup and the unrelated `hast` package; `oxlint`, `oxfmt` and `puppeteer` moved to devDependencies (locked versions unchanged) - Typo fix in the Tessera cover alt text; removed unused `math`/`mermaid` flags from two posts ## Deployment notes - **`SITE_URL` is now required**: the build fails with a clear error if it's missing. - **Puppeteer is a devDependency now**: Nixpacks installs dev dependencies for the build by default, but check that Mermaid diagrams render on the first deploy (the Standard Model post has one). ## Testing - `tsc --noEmit` and `bun run lint` pass - `bun run build` passes; all 81 pages are generated statically - Smoke-tested `next start`: posts, tags, categories, feed, sitemap and OG images return 200; unknown tags and routes return 404 - No block elements nested inside `<p>` in any built page Reviewed-on: #1
