Using the approved rough cut, render a short caption sample with fast speech, short words and a long word.

Show one word at a time, lowercase, without punctuation. Use the actual Inter Medium 500 font at 84 px on a 1080 x 1920 canvas, white with a 3 px black stroke. Keep the position consistent and avoid my face and the target app's controls. Scale the preset if the canvas differs.

Check that timings follow the edited audio and the correct font and weight loaded. Keep the readable transcript separately. Return the actual sample MP4 for phone-size review before the full render.
