swayfx: with `border pixel` the visible line is child_border, not `border`
(which only paints title bars). Focused child_border was $base00 = black on
black, i.e. invisible; both are now the same gray.
keybinds: restore `floating_modifier $mod normal` (was `none`) and drop the
`pkill -RTMIN+10 i3blocks` tail from the volume binds -- i3blocks is not in
use, waybar is.
windows: drop a stray trailing semicolon; waybar: remove the unused
sway/submap module.
