Context. The monthly sales line is going on a slide and the brand color is red. Styling is part of the job.
Your task. Write make_styled_line(months, sales) that plots sales as a red line, sets a title mentioning "Sales", and returns the axes.
Example. color="red" in the plot call; title like "Monthly Sales".
Notes. Use the color name "red" exactly (not a hex code) — the checker reads back the color you set.
