 - **Windows-only**: Engine uses `ctypes.windll.kernel32.SetThreadExecutionState`. Use `--simulate` on the CLI, but note the engine itself will still call the API. Tests mock it automatically.
 - **`--simulate` is NOT a dry run**: It enables a 1px mouse jiggle (right then left) via `SendInput` to fool presence detection in Teams/Slack/Zoom. The engine still calls `SetThreadExecutionState` either way.
 - **Python 3.10 needs `tomli`**: `config.py` falls back from `tomllib` (3.11+) to `tomli`. Not in `dependencies` - users on 3.10 must install it manually or config loading will fail.
-- **Animation at 8 FPS**: `animations.py` drives `Rich.Live` at 8 FPS. The `FPS` constant controls refresh rate.
+- **Animation at 10 FPS**: `animations.py` drives `rich.live.Live` at 10 FPS. The `FPS` constant controls refresh rate.
+- **TTY vs non-TTY in `run_display`**: On a TTY it runs a Rich `Live` redraw loop with `q`-to-quit (via `msvcrt`). When stdout is piped/redirected it prints one status line and sleeps until the engine stops, so log output stays clean.
 - **Duration expiry in tray mode**: Engine fires an `on_stop` callback on a separate daemon thread to avoid self-join deadlock.

 ## What you get
 
-The CLI mode gives you a live dashboard running at 8fps with procedurally generated steam wisps rising from a color-gradient coffee cup, a rippling liquid surface, a border that breathes through cyan shades, and coffee puns that type themselves out with a blinking cursor. Timed sessions get a progress bar. Is any of this necessary? No. Did we do it anyway? Obviously.
+The CLI mode gives you a single-line status: a braille spinner, what it's doing, how long it's been doing it, and a rotating coffee quip underneath. No dashboards, no ASCII art, no breathing borders. It reflows on narrow terminals, drops styling when `NO_COLOR` is set, and quits on `q` or Ctrl+C.
 
 There's also a system tray mode if you'd rather it just sit in the corner and do its job quietly. Coffee cup icon, right-click menu, notifications when a timed session ends.

-The steam is procedurally generated - 10 wisps rising with sine-wave drift, fading from `)` near the cup to `·` at the top. The coffee has a three-tone brown gradient. The liquid surface ripples. The quips type themselves out letter by letter with a blinking cursor. If you set a duration, a progress bar fills up next to the cup. The border breathes through cyan shades at 2Hz. All of it runs at 8fps and the entire animation state is a pure function of the frame counter. Nobody asked for this.
+The spinner is a 10-frame braille cycle ticking at 10 FPS. The quip is held back for the first 5 seconds so startup isn't noisy, then rotates every 90 seconds from a pool of ~120 puns seeded per-session so each run feels different. Narrow terminals (under 50 columns) drop the "left" suffix and quit hint. `NO_COLOR` disables the cyan accent and dim styling. Piped or redirected output skips the live redraw and prints one line.
