+ WEB TOUCH (one finger): a tap is LOOK, the same action as R; a drag

+               were Git-tracked and embedded when the web build was made.
+               The published launcher is a real Pardes terminal dump of
+               `git ls-files '*.zig'`: every listed path opens, and the
+               opened source uses tree-sitter syntax colors.
+               A touch beginning on a tagline or pane separator instead
+               latches a left-mouse gesture, so layout drags never scroll.
+               Touch circles/trails and the LOOK flash appear only while
