.sb-tabbar now reserves 64px on the right, the same way .sb-header already
does for the title: the ✕ is a Gtk.Overlay child, so it claims no layout
space and the tab row grew straight under it once the row got wide enough
(the "General Settings" pill was overlapping the button's circle).
Also documents, next to `config vicinae` in hyprdrive's updater.conf, that
the cosmonaut.toml this deploys to ~/.config/vicinae/ is inert — vicinae only
reads named themes from ~/.local/share/vicinae/themes/, and silently falls
back to its default grey theme when the file isn't there. That is exactly
what happened on this machine: the theme was added after hyprdrive.sh last
ran, so the launcher had been rendering the stock grey palette.
