Scaffold 0.7.0

Backport release: generic improvements from new features developed for Scaffold-based websites, plus Node 24 and minor dependency updates.

Before merging

• Node 24 required. engines.node is now >=24.0.0 and netlify.toml pins NODE_VERSION = "24". Node 22 reached end of active support; Netlify builds switch over with the pin. Update your local Node (nvm install 24) before running npm install.
• Dependencies bumped to current minors: Astro 7.4, the Netlify adapter 8.2, React 19.3, Tailwind 4.3, plus @astrojs/rss as a new dependency. Run npm install after merging. If the first build fails with Cannot find package '@netlify/blobs', run npm dedupe — npm occasionally nests that package under the adapter where Astro's session storage can't resolve it.
• .pages.yml conflicts are likely if you customised it. New in this version: a settings: block (content merge + commit message templates), seoTitle/seoDescription on every content collection, a email field in Site Settings, a stricter slug pattern, and the extraInfo person field is gone. Take Scaffold's version as the base and re-apply yours; the update script re-syncs your category lists afterwards.

Action needed

• Delete public/robots.txt and public/llms.txt if you have them. Both are now generated routes (src/pages/robots.txt.ts, src/pages/llms.txt.ts). public/** is protected, so the update script does not remove them for you.
• Slugs must be lowercase and non-empty in the CMS. The permalink/ID pattern changed from ^[a-zA-Z0-9_-]*$ to ^[a-z0-9_-]+$. Existing content with uppercase permalinks still builds, but Pages CMS will refuse to save that entry until the permalink is lowercased (and the auto-permalink workflow then renames the file).
• FormField.astro and PageSection.astro are removed. If you imported either in your own components, copy the old file from your git history into your site.
• People extraInfo is removed from the schema and the CMS.
• Card images in CardSection now have alt="" because the card title follows as a heading (screen readers were reading the title twice). If you put meaningful, non-title imagery in cards, override in your own CardSection.

Changes in behavior

• Page titles get the site name appended (About | Your Site) unless the title already ends with it.
• Preview builds (PUBLIC_PREVIEW=true) now render noindex,nofollow, robots.txt disallows everything, draft content gets a DRAFT label, and an orange frame with a "Preview" badge is drawn around the page.
• Whole cards are clickable (Card, ArticleCard, article index): the title link stretches over the card. Nested links inside a card need relative z-10 to stay clickable; Scaffold's own cards already have it. Card.astro is now position: relative, and CardSection's grid uses .cards-grid from scaffold.css (equal row heights; a lone card or pair is centred — center={false} to opt out).
• Table of contents picks the active heading from scroll position instead of an intersection band, and a long TOC scrolls inside the sticky sidebar. TOCs are capped at two levels (h2 + h3).
• Rich search caps results at 10 per category, no longer flashes its skeleton when opened, and the nav search button shows a ⌘ K / Ctrl K hint on md and bigger screens.
• Sitemap excludes /api/*, /og/* and non-HTML endpoints, and article URLs carry <lastmod> from publishedDate.

New bits

• SEO pass. Head.astro emits og:type (website / article / profile), og:site_name, og:locale, image type/width/height/alt, article:published_time / article:author / article:section / article:tag on articles, and name="twitter:*" tags. Every page carries a schema.org JSON-LD graph (Organization + WebSite) and detail pages add Article, Person or CreativeWork nodes (@utils/jsonld, atoms/JsonLd.astro). Layouts accept ogType, noindex, jsonLd and article props.
• seoTitle / seoDescription on pages, articles, docs, people, partners and resources override the browser-tab title and meta description; email in Site Settings feeds structured data and llms.txt.
• Fixes: Heading styles follow level even when as renders a different tag; the fallback OG image URL is absolute on the site URL (not the request URL); auto-excerpts skip a leading [EmbedLink](…); docs prev/next and sidebar use getDocUrl; the search index uses getArticleUrl / getDocUrl; the search legend punctuation.
• Feeds: /rss.xml (published articles), /robots.txt, /llms.txt generated from your content; <link rel="alternate"> and <link rel="sitemap"> in Head.
• Navigation: dropdown chevron rotates when open; top-level active links carry aria-current="page".
• SectionHeader compact prop; CallToActionSection accepts a default slot (rendered only when used).
• Pages CMS: settings.content.merge keeps keys the CMS doesn't manage; commits are stamped "(via Pages CMS)"; the pages list shows the permalink column.
