Make galleries (and maybe slides?) work with base theme #1764
Description
It's a bit shameful to ship a "major" feature like galleries that doesn't work at all with the base theme, from which we recommend theme authors should fork.
This will probably be a lot of work, but I am calling it a blocker.
- galleries WIP in Implement Galleries as JSON+JS for all themes #1765
- lightbox
- slides TBD
