The prompt

Build a feature flag management panel with Tailwind CSS. The header holds the flag name in monospace with a small "boolean" type pill, a muted description line, and a prominent switch on the right showing the flag on in production. Below, three environment rows in a bordered card: each has the environment name, a small state pill, a rollout percentage with a range slider, and a muted line giving how many users that represents. Then a targeting section listing two rules as bordered rows with a condition in monospace, a small "then serve true" clause and a delete cross, plus a dashed "Add a rule" row. Finish with an audit strip of three recent changes, each with an avatar, a sentence describing the change and a relative timestamp. Then add JavaScript that keeps each percentage label and its user estimate in sync with its slider, and flips the environment pill between off, partial and full.
