feat: rebuild mintel.me as a single-page freelance site

The site now presents one freelance developer on one page: hero, introduction,
four typical cases (developer for a product, make an app reliable, automate a
process, a website) with what you get, how it runs and what it costs, a
process automation section, technology and project fit, how I work, two live
references, questions and contact.

- Hero and closing headline are drawn from running binary digits.
- Each case explains its four steps with an animated drawing; the automation
  section shows example workflows with work travelling between systems; a
  pipeline run shows what a test catches before a release.
- Contact is one email address, kept in parts and assembled in the browser so
  it never appears in the page source (src/domain/email.ts, spec first).
- Imprint and privacy pages added.
- The old site (blog, case studies, contact form, fixed-price pages, video
  rendering and related scripts) is removed. Its URLs redirect to the homepage.
- The deploy smoke test checks the legal pages and the redirects instead of
  the removed case study.
- Dev scripts use docker compose v2.
