+// Presentation mode, the same module the DP-1 bar runs.
+//
+// `statusctl presentation watch` streams waybar JSON on every change: it
+// already emits an empty text and a class of activated, deactivated or down,
+// so the icon is chosen in CSS from that class and no format is needed here.
+// Dropping format-icons is the whole difference from the DP-1 copy, which
+// draws the same two states as Nerd Font glyphs.
+//
+// `down` means the state file is missing, which is not the same as off: the
+// mode cannot be read at all. It gets its own icon rather than borrowing the
+// off one, so a broken watcher does not read as a working bar.
+//
+// statusctl talks to files under XDG_RUNTIME_DIR rather than to quickshell,
+// so this keeps working while the shell is down.
+// The format is a single space, and it has to be something. It defaults to
+// "{text}", statusctl emits an empty text, and waybar draws no widget at all
+// for a custom module whose formatted output is empty: not an empty pill, no
+// pill. A space gives the label real content to be allocated for, shows
+// nothing itself, and leaves the icon to the CSS background.
