The README opened without mentioning that the thing is deployed, and the HTML
document carried a title and nothing else — no description, no link preview.
Both matter more now that there is a public URL to land on.
README: the live link up top; the object card and the measured/derived split
from #3, which were built but never written down; `shared/format/`, `public/`
and `.github/workflows/` in the layout.
index.html: a description, a theme colour matching --color-void so the browser
chrome does not flash white around a black sky, and Open Graph/Twitter tags so
a shared link renders as something other than a bare URL. Those URLs are
absolute and name the deployment outright — a scraper has no document to
resolve a relative path against, so they cannot follow <base> the way the rest
of the app's paths do. A custom domain later means editing these three lines.
The preview image is the galactic view, copied into `public/` so it is served
by the site itself rather than linked out to raw.githubusercontent.
Verified: the built document keeps every tag, the base href still rewrites to
/star-map/, the image answers 200 at the path the og:image names, and both the
root and a deep link still render. 527 tests pass.
