Portfolio migration: GitHub Pages (Jekyll) -> Vercel (Eleventy)

This folder replaces docs/ in your repo wholesale. Jekyll is gone: no Gemfile, no Ruby, no bundler. The site now builds with Eleventy (Node), which reads the same Liquid templates and Markdown your content was already written in. The build was run and verified: all 12 posts, all pages, identical URLs, sitemap included.

What changed

• _posts/ renamed to posts/ with posts/posts.json supplying layout, permalink (/blog/.html, same URLs as Jekyll), and the collection tag. Post front matter unchanged except date formats normalized to ISO (Eleventy rejects Jekyll's "10:00:00 -0400" style).
• eleventy.config.js and package.json replace Gemfile/bundler. _config.yml is no longer used (kept nothing from it that matters; site metadata now lives in _data/site.json so Portfolio of Ed Grzetich etc. keep working).
• Layouts and pages: page.title/description/etc become bare variables, include syntax quoted, blog loop uses collections.posts. Content prose untouched.
• sitemap.liquid replaces jekyll-sitemap, with real per-page lastmod dates from post dates.
• CLAUDE.md, GEMINI.md, feat-api.md, resume.json, resume_api.py, robots.txt, assets/, and yobitel/ are passthrough copies served verbatim, matching Jekyll's behavior for front-matter-less files. The yobitel Markdown stays raw Markdown.
• All the previous content edits are included: Senior Technical Writer objective in both resume JSON copies and the API demo, past-tense AWS paragraph, Vercel analytics scripts in the default layout, vercel.json content-negotiation rewrites.

Local preview (optional but recommended once)

cd docs && npm install && npm run serve

Then http://localhost:8080. npm run build writes _site/.

Vercel project settings

• Root Directory: docs
• Framework Preset: Eleventy (or Other)
• Build Command: npm run build
• Output Directory: _site

Node projects are Vercel's native path; no runtime surprises like the Ruby build. Add docs/node_modules and docs/_site to .gitignore.

Remaining steps (unchanged from before)

1. Deploy, verify preview URL: pages, blog permalinks, /yobitel/resume.md returns raw Markdown.
2. Enable Web Analytics and Speed Insights in the Vercel dashboard.
3. Domains: add grzeti.ch in Vercel first, then at your DNS provider replace the four GitHub Pages A records (185.199.108-111.153) with Vercel's apex A record (dashboard shows the value, currently 76.76.21.21); www CNAME to cname.vercel-dns.com if used. If DNS is behind Cloudflare, set those records to DNS-only (grey cloud).
4. After grzeti.ch serves from Vercel (response header says server: Vercel): repo Settings -> Pages -> Source: None, and delete the CNAME file. Ignore GitHub's "custom domain removed" email.
5. Verify negotiation on the live domain: curl -s -H "Accept: text/markdown" https://grzeti.ch/yobitel | head -3
6. Submit https://grzeti.ch/yobitel/ on the Yobitel application.
