Images render as <figure>, which isn't allowed inside <p>. The unwrap
plugin only handled paragraphs containing a single image, so a label
followed by images on the next lines (as on the Projects page) produced
invalid HTML and a hydration error. Split such paragraphs instead.
- Replace the create-next-app README with real project docs (features,
env vars, frontmatter schema, Markdown extensions, deployment)
- Drop ESLint (unused by any script; oxlint is the linter) and the
unrelated 'hast' package; move oxlint, oxfmt and puppeteer to
devDependencies (locked versions unchanged)
- Extract PostList, used by the tag and category pages
- Use shared Intl formatters for post dates, pinned to Europe/Prague so
the build server's timezone can't shift dates
- Use <h1> for the tag/category page headings (same styling)
- Remove math/mermaid flags from posts that don't use them; fix a typo
in the Tessera cover alt text
- aria-labels on share links, sidebar social links and mobile nav icons
- aria-current on active nav links
- CopyButton: React state instead of innerHTML mutation, clipboard error
handling, accessible label and a polite live region for feedback
(Related code-block and image-caption a11y fixes landed with the
ImageWrapper/CodeWrapper rewrite in the previous perf commit.)
- Add sitemap.ts and robots.ts
- pageMetadata() helper: consistent title, canonical URL, Open Graph,
Twitter card and feed alternate on every page
- Generated OG images: a site card, and per post either the cover image
or a branded title card (pre-rendered at build)
- BlogPosting JSON-LD on post pages
- Fail fast with a clear error when SITE_URL is missing
Content loading:
- Validate post frontmatter at build time and normalize dates to ISO
(fixes invalid <time datetime> values)
- Add draft: true support (drafts only render in development)
- Cache markdown rendering so metadata and page share one render
- Replace the three copy-pasted about/projects/setup pages with a shared
MarkdownPage component
- Only preload the post cover and latest-post image instead of every image
- Drop in-post image quality from 100 to 90 and add responsive sizes
- Downscale 2940px screenshots to 1800px; convert linkboard-old to WebP
(3.1 MB -> 60 KB)
- Make CodeWrapper a server component; only CopyButton ships to the client
- Pin the Mermaid CDN script to an exact version for reproducible builds
- Slugify tag/category static params so pre-rendered pages match links;
disable dynamic params and return a real 404 via notFound()
- Drop bogus generateStaticParams from the tags/categories index pages
- Add a styled not-found page
- Sort 'Recently updated' by last modification before slicing
- Atom feed: correct rel=self URL, use updated dates, valid content type
- Swap no-js -> js class in an inline head script before first paint
- Markdown links: only route internal paths through next/link and
tolerate missing hrefs
