Card-mod to change dashboard background

Can I use card-mod to change the background of a sections dashboard?

The below changes the background of a card in my dashboard:

views:
  - title: Calendar
    sections:
      - type: grid
        cards:
          card_mod:
              style: |
                ha-card {
                  background: url('{{ states('sensor.unsplash_random_image') }}')
                }

But, I want the image as the background for the entire tab/section. If I hard code a url I can do it with:

    background:
      image: https://picsum.photos/1000

However, I can’t seem to get my template working in this situation.

Thanks.

That is amazingly comprehensive, thank you for putting it all together.
Saddly, I still can’t work it out (but that is on me)! I’ve posted details there, hopefully someone can end my struggles!
