an icon, so the tab is not blank

The export declared no icon and the bucket had none to serve, so /favicon.ico
answered 404 and every Tabs pane sat behind a blank tab — in a product whose
whole premise is telling one tab from another.

public/ carries the Hanzo mark from @hanzo/brand as .svg and .ico, and the
layout declares both. The .ico is there because a browser asks for it whether
or not a page names one, and a bucket has no server to answer with anything
else.
