Same treatment as the sso-manager-node companion PR: replaced the
generic jekyll-theme-cayman theme with a custom layout mirroring the
actual app UI -- dark fixed navbar with the theta42 logo, Bootstrap 5
+ Font Awesome (same stack the app uses), content in a card, dark
footer matching bottom.ejs. Keeps this repo's own favicon.svg
(confirmed genuinely distinct SVG artwork from the shared theta42
logo, not a duplicate) as the browser-tab icon.
- New cross-page nav (Home/Installation/Architecture/API/Docker/
Contributing/Changelog).
- SEO: jekyll-seo-tag + jekyll-sitemap, per-page meta description,
OG/Twitter card tags, canonical URLs, JSON-LD, sitemap.xml,
robots.txt.
- Mobile: Bootstrap's responsive grid + collapsible navbar; the
screenshot pairs in index.md stack to full-width below 576px.
Verified with a real Jekyll build (jekyll/jekyll Docker image) +
Playwright: desktop and mobile (375px) screenshots, mobile nav
toggle, active-link highlighting, zero console/page errors, and
confirmed real SEO output + the correct (non-shared) favicon via curl
against the served site.
