The web UI used two shapes for an empty region: the dashed .empty-state
box on some lists and bare .muted paragraphs on others. Some of those
empty states also repeated controls that were already in the filter row
directly above them.
This standardizes full-region empty states on .empty-state, keeps the
compact line inside sidebars, cards, trees, and table cells muted, and
removes the links that duplicated the filters: the merged/closed change
links, the closed-issue link, the clear-filter links, the users directory’s
“Show everyone”, and the signed-out home page’s duplicate sign-in buttons.
The issue and change discussion empty state no longer prints a CLI command. The composer is on the page, so a reader can comment without cloning.
