@dhogan8 I was thinking maybe we could use a different bg colour here to distinguish this banner from the previous one. Any thoughts on that?

@oalders I haven't spun up the dev environment for this branch yet, but is this replacing the The Perl Toolchain Summit needs more sponsors.... banner or going underneath it?

[oalders]

@dhogan8 this will be replacing it. That banner was removed in a previous commit, but it hasn't been deployed yet. My concern is that if it looks a lot like the previous banner, people won't pay attention to it.

How about #006081?

I've amended the commit to tweak the background colour to #006081 👍

Rebased my branch against upstream master

Looks like there's some issue in the CI related to code coverage uploads?
