Community header plans

[kpsherva]

• Should we harmonize all the community headers to one style? -> not at this point

• Do we have the grayed out zenodo header for any community that is themed? meaning that is has either colors specified/custom templating applied or both) -> not at this point

• Should the community frontpage text (hero section) be editable for the user? -> not for now, until we know what more variables are needed

• style community invitation (when arriving from "my dashboard") -> not for now, to be tested

• style community inclusion request (when arriving from "my dashboard") - probably it shouldn't be done, since the visual identity should not be added before accepting the record as a part of the community -> not for now, to be tested
