Enlarged mode is basically like using the theme at ~110% zoom. It can be
enabled by setting `enlarged = true` as a config parameter. Other
changes are only minor fixes that shouldn't significantly impact
existing sites.
- If `blogs` isn't set in the config file, `blog` is treated as a blog, to
avoid breaking existing sites
- If it is, only sections listed are treated as blogs, possibly
excluding `blog`
- Differences include comments, but also hn/lobsters links, time to
read, and tags (possibly non-exhaustive)
