With no absolute url in _config.yml, the theme's SEO layer (added in jekyll-vitepress-theme 1.9) skips canonical URLs, JSON-LD, and sitemap.xml, warns on every build, and emits llms.txt with relative links. Setting the production origin turns all of that on: pages get self-canonicals, robots.txt advertises the sitemap, and llms.txt links become absolute. The canonical_latest plugin now reads the origin from site.url instead of only its hardcoded constant, which remains as the fallback for builds where url is overridden or unset (jekyll serve rewrites it to localhost in development). Its /latest/ canonicals still take precedence on the numbered twin collections, which search engines can now use to dedupe the /8.x/ and /latest/ copies.

The theme emits og:image:width/height and a stable og:image:alt only when jekyll_vitepress.seo.image is set. HexagonSticker.png is already 1200x630, so point at it explicitly per the theme's production minimum. Co-authored-by: Claude <noreply@anthropic.com> Signed-off-by: Michael Harp <mike@mikeharp.com>

@binford2k Thanks, good pointer. Checked the 1.9.1 source: the seo hash is optional (config_for returns {} when it's absent and the image falls back to logo), so url alone already gets canonical, og:, twitter:, JSON-LD, sitemap, and robots. What it does add is og:image:width/height and a fixed og:image:alt. HexagonSticker.png is already 1200×630, so I pushed a second commit setting seo.image per the theme's production minimum and confirmed those tags now render. |

Since jekyll-vitepress-theme 1.9, the theme ships an SEO layer that can emit canonical URLs, JSON-LD,
sitemap.xml, arobots.txtsitemap pointer, andllms.txt/llms-full.txt. Without an absoluteurlin_config.ymlmost of that is skipped: the build warns every run, no sitemap is generated, and the llms outputs use relative links.This sets the production origin in
_config.ymland updates thecanonical_latestplugin to read the origin fromsite.urlrather than only its hardcoded constant. The constant remains as a fallback for builds whereurlis unset or overridden (jekyll serverewrites it tolocalhostin development).Verified with a full local build:
