Superset wears the new design; site charts sit as boxes (PD-24 to PD-26)

Theme tokens for the slate surfaces and borders, the logo with the green Y, chart boxes at 16 px
with the card shadow. Full figures with the unit in the subheader; every layer of the tabs
transparent, so the site's charts sit as boxes in Firefox and Safari too. The Overview gets a Sites
filter and the period's scope returns to the time charts (PD-25). The embedded frame can shrink again.
A change to the image's inputs: Superset rebuilds on the next deploy.

Bands: Superset. Rules: 2.
