A terminal runs a command: it types in, then the log streams line by line with a cycling spinner and an accent success line

This is the format it was composed for. Switch above to see it lay itself out for another — same animation, re-arranged for the frame.

A terminal window running a command. Window chrome with traffic lights and a mono title, a prompt glyph, then the command types itself in and the output streams out line by line — a spinner cycling while a step runs, dim detail lines, one accent-coloured success line at the end, and the prompt coming back with a blinking caret. Tight line heights, generous window padding, true monospace throughout, and each output line should fade up and rise a few pixels as it lands.
