The Moonlit Book Cart puts a decorative opening quote before its featured reader note. The quote is presentation, not part of the note text in index.html.
In style.css, .card:first-child::before selects a generated piece before the content of the first card. content: "“" creates it; without content, ::before has nothing to display. The gold color makes the new mark easy to spot. The second card stays unmarked.
Checkpoint: one gold opening quote appears on the first dark card, not on the second.
Change the quote's color to another visible color and run Preview; restore #fbbf24 before the exercise.
Change one CSS value, then run the preview.
Restore the original value before continuing.
