- 7 categories now listed with name, blurb, post count and a
per-category terminal-style SVG illustration (CategoryArt)

- language switch wired both ways (EN <-> ZH)
Update hello-world post, homepage, about page, and zh landing to say
website design & development (primary) + email hosting (side offering),
not 'email-hosting business'.

- Derive lang from folder (posts/zh/* -> zh, else en); remove lang: frontmatter
- Change post route to [...slug] to capture nested zh paths
- Add nav language switcher (EN <-> 中文) + /zh/ landing page
