Watch the bottom-center of this window: a small, faint
translucent pill should fade in and track the macro's current action,
e.g. pill-status-demo | evaluate, then
pill-status-demo | expect_text text=pill probe, and so on.
The corner badge in the bottom-right is the existing per-browser indicator you already had — the new pill is the centered one. Both share a stable color seeded from the launch label.
