Every route was missing rel=canonical, and 15 of 22 routes shared a title/description. Adds a pageMetadata helper (docs) that emits a self-referencing canonical, og:url/og:type/og:site_name, and correct per-site card images, then applies it across the docs routes; diffshub home/layout get the same OG fields and a canonical. Also fixes the trees title collision (all 10 routes shared one title) and trims the 70-char /theme title. Canonicals are declared per-page rather than in the layout so query-string variants (e.g. /playground?theme=) collapse onto one indexable URL without child routes inheriting the wrong canonical.

Summary
rel="canonical". Adds a self-referencing canonical to all docs routes and the diffshub home. Canonicals are declared per page, not in the layout, so query-string variants (e.g./playground?theme=…) collapse onto one indexable URL without child routes inheriting the wrong canonical."Trees, from Pierre"), gives every route its own title/description, and trims the 70-char/themetitle to ~49 chars.og:url,og:type, andog:site_namesite-wide.apps/docs/lib/page-metadata.tscentralizes this because Next.js replaces nestedopenGraph/twitterobjects from parent segments instead of deep-merging, so each page must restate its full card.Excludes JSON-LD structured data and demo/pipes noindex by design (kept for separate follow-ups).
