 `~/.local/share/moq-studio`) on Linux, and `%APPDATA%\moq-studio\data` on
 Windows, apart from the scene file, so a scene file moves between machines
 without one operator's keys. A key bound to a scene follows it when renamed in
 the studio.
 
+## Effects
+
+The window draws effects of its own, which never reach the program, a
+published scene, or a recording:
+
+- The Program monitor glows red while the studio is connected to a relay,
+  the recording dot pulses, and each cut or transition, from its button or a
+  hotkey, bursts on the monitor.
+- The **Cut** button is polished metal that ripples under the pointer, the
+  Hotkeys panel shows each bound key on a keycap, each panel has a faint grain,
+  and first launch draws its screen over a soft gradient.
+- The Health panel and its tab pulse amber while the worst problem is
+  degraded, and flicker with electricity while it is unhealthy.

+**View > Effects** sets how they move: **Full**, **Reduced**, which holds each
+on one still pose, or **Off**. Until you pick one it follows the system's
+reduced-motion setting: Reduce motion on macOS, animation effects on Windows,
+and on Linux the desktop's, through its Settings portal.
