Condensed from einfach-produktiv.com/ueber-bjoern/ — trimmed,
emoji-free, rewritten in the site's own voice rather than the
original's. Same hand-styled article treatment (H2/Quote/CTA-card)
as /lebensuhr and /3x3-system since it's not CMS-backed either.
Reuses the existing about-author.jpg portrait already used on blog
posts.
