Build an FAQ accordion list with Tailwind CSS using native details/summary elements: each question is a summary row with a plus icon that rotates when open, and the answer sits inside with comfortable line length. Style the open state with a left accent border, keep only one item open at a time by wiring a small script that closes siblings, and make sure the whole summary row is keyboard-operable without extra ARIA.
