Create a minimalistic blog page template

- This task is a generic one to start with the blog space creation.
- Use https://bikepacking.com/gear/100-discounts-for-members/ as an example. I love this website and want to invent something similar.
- At this stage, build a blog for one person. The multi-author blog will be considered later.
- Keep the blog on the primary domain (not a subdomain) and use the unified UI components library.
