Diagnosed live in a VM: the bar rendered twice (two stacked rows). `hyprctl
layers` showed two `gtk-layer-shell` bar surfaces owned by two different eww
pids — an `eww daemon` and an `eww open bar`. The monitor count was correctly 1,
so the per-monitor loop was not at fault.
Root cause: ewwstart.sh started `eww daemon` and then immediately ran `eww open`
in a loop. The first `eww open` frequently ran before the freshly-started daemon
was ready, so it spawned its OWN second daemon and drew a second bar.
Fix (all three DE variants — hyprlua, hyprland, niri):
- Drop the separate `eww daemon`; rely on `eww open` to auto-start the daemon and
block until the window is mapped, so the first call establishes a single daemon
that the rest reuse (no race, no second daemon).
- killall eww + short settle before opening, so a reload starts clean.
- hyprlua/hyprland: count monitors via `hyprctl monitors -j | jq length` instead
of the fragile `hyprctl monitors | grep ID | wc -l`.
- export GTK_THEME (the bare assignment never took effect).
