Tune CI software stream profile

 - **Start on the default for compatibility.** `h264-software` works without requiring the hardware encoder, but full-resolution latency can be high.
 - **Switch to `h264` on local Apple Silicon when hardware encode is available.** Hardware H.264 gives the smoothest local preview with the least CPU.
 - **Switch to `h264-software` when the hardware encoder stalls or is unavailable.** The encoder scales the longest edge to 1600 pixels, can climb toward 60 fps, and backs off dynamically under encode latency.
-- **Use `--stream-quality ci-software` for Studio providers on virtualized CI Macs when hardware encode is unavailable.** This profile uses software H.264 at a 960-pixel longest edge, targets 24 fps, lowers bitrate pressure, and favors fresh frames over full-resolution sharpness.
+- **Use `--stream-quality ci-software` for Studio providers on virtualized CI Macs when hardware encode is unavailable.** This profile uses software H.264 at an 844-pixel longest edge, targets 20 fps, lowers bitrate pressure, and favors fresh frames over full-resolution sharpness.
 - **Use `h264-software --low-latency` only when you need the older extra-conservative software profile.** It caps at 15 fps, uses a single pending frame, reduces the longest edge to 1170 pixels, and backs off before software encode latency turns into seconds of stream delay.
