How can I determine if a post is in one of the mainSections in config.toml?

How can I determine in head.html if a post is in one of the mainSections as defined in config.toml?

In config.toml, I have

mainSections = ["posts", "blog"]

What I want to do is add a meta tag in head.html if the post is in the mainSections “blog”.

I.e., for taxonomy pages, I use this in head.html to add a noindex meta tag:

{{ if .Data.Singular }}
<meta name="robots" content="noindex,nofollow">
{{ end }}

How can I do this for “blog”? This is what I want to do, but it obviously doesn’t work:

{{ if .Data.Blog }}
<meta name="robots" content="noindex,nofollow">
{{ end }}

Thanks!

Assuming this content structure:

content
├── blog
│   ├── blog-1.md
│   └── blog-2.md
└── posts
    ├── posts-1.md
    └── posts-2.md

with config.toml

[params]
mainSections = ["posts", "blog"]

layouts/_default/single.html

{{- if in .Site.Params.mainSections .Type -}}
  ...
  ...
{{- end -}}

Thanks, this targets both blog posts and posts posts with the content structure above:

{{- if in .Site.Params.mainSections .Type -}}

And curiously, at least for posts, not the main posts page, but only single posts.

How would I target only the main blog listing and blog single posts and not posts posts?

I’m using this in head.html, not single.html.
