- New keyword-focused <title> and meta description.
- Add robots (index, follow, max-image-preview:large) and og:locale.
- Add schema.org JSON-LD (WebSite + WebApplication) with feature list,
free/MIT offer and GitHub sameAs — non-executable data block, so it
passes the strict script-src CSP.
- Regenerate the 1200x630 social card without the redundant URL line.
Link previews (LinkedIn, X, etc.) were broken: og:image pointed at a
GitHub-hosted favicon (.ico, too small, likely 404) and og:url pointed at
the GitHub repo instead of the live site.
- Add a branded 1200x630 social card at assets/og-image.png.
- Point og:url/canonical at https://securebit.chat/ and og:image at the new
PNG via absolute URLs; add og:image:width/height/type, og:site_name,
og:image:alt and twitter:image.
- Refresh the meta description to match the product (no longer version-stamped).
