Pattern

Page head and metadata

What every page tells browsers, search engines, social networks, and agents: one title, one description, one card.

Rules

Title: “Page Topic • Niklaus Gerber” (•) in <title>, og:title, and twitter:title. The home is just “Niklaus Gerber”.
Description: One per page, 110 to 155 characters, full sentences. The same text in meta description, og:description, twitter:description, and JSON-LD; for an article also in its Thoughts row, feed.xml, and llms.txt.
Canonical: https://niklausgerber.com/…/ with a trailing slash, no www.
Share card: 1200 × 630, generated per page by make-share-cards.sh (see brand/README.md, Share card).
Structured data: JSON-LD per page type: WebSite, ProfilePage, and Person (home); WebPage (content pages); CollectionPage and ItemList (Agents); MobileApplication, Offer, and FAQPage (Hirsla); Book (Unresolved); BlogPosting (articles). Every page but the home carries a BreadcrumbList; on second-level pages it ends with the current page.
Theme colour: #F5F3EF light, #121212 dark; the night page #0a0a0b.
Agents and feeds: Every public page is in sitemap.xml and llms.txt; articles are in feed.xml.
Scripts: No inline script except JSON-LD; vt.js in the head, site.js as a module.
