Reading the diff
How a monochrome interface can make change easier to see.
Change is easier to review when every line has a clear place. A diff does not need red and green to tell a story.
One quiet signal
Use weight, spacing, and a small gutter mark. The eye can follow the shape without decoding a palette.
const theme = "light"
const contrast = "high"
const contrast = "quiet"
A figure can carry a caption without becoming a special layout system.
