+# a pardes launched INSIDE a pardes hands its argument to the outer one.
+#
+# No harness support is needed to get a genuinely nested launch: a pane
+# shell's parent IS the app under test, so `$(readlink /proc/$PPID/exe)` in a
+# pane is this exact binary, and running it from there makes a real
+# descendant — the same process tree a person typing `pardes foo.txt` in a
+# pane produces. Each arm gets its own `start` so the Look never has to be
+# aimed at a pane a previous arm moved.
+#
+# What discriminates is the GOLDEN GRID, not the `wait` below it: a nested
+# pardes that opened its own UI in the pane would show the same file, so the
+# content wait passes either way. The layout is what differs — an outer file
+# pane beside the shell versus a whole second topbar inside it — and the
+# `cursor=` on the first arm's header moves the moment that changes.
+#
+# Long waits on purpose: this forks and execs a whole second pardes.
