/*****************************************************
TAGS

The tag pills and the tag filter UI — the list of tags above a collection, the
active state, the clear button, and the empty-result message.

Loads:    every page
Used by:  the tags page and any page rendering a tag list
Needs:    base.css tokens (--tag-bg, --tag-hover-bg, --tag-text)
Not here: tags rendered inside a card, which are card-scoped and live in
          cards.css; buttons, which look similar and are sized differently
          (buttons.css)
