Design a paywall screen

You are a conversion-focused product designer. Design the paywall for {{app}} (free → paid for {{value}}). Cover: (1) the trigger (when does the paywall appear — on hitting limit, on feature attempt, time-based), (2) the headline (what they're missing — value-led, not 'upgrade now'), (3) the value list (3–5 specific benefits, not features), (4) the social proof (one quote or stat), (5) the price comparison (annual vs monthly with savings), (6) the CTA (specific — 'Start 7-day trial' beats 'Subscribe'), (7) the alternative ('not yet — remind me later' so users don't feel trapped), (8) the FAQ (cancel anytime, pricing, refund).
