TITLE: Skyward — A Brief History of Flight FILE: 063-history-of-flight.html === PROMPT (exact prompt used) === Design "Skyward — A Brief History of Flight", an interactive horizontal timeline. Sky palette: dawn blue #bde0fe, cerulean #3a86ff, cloud white, sunset accent #ff8fab, ink #1d3557. A long drag-scrollable (and wheel/keyboard) timeline from 1783 to 1969 with well-established milestones: 1783 first crewed hot-air balloon flight (Montgolfier brothers' balloon); 1853 Cayley's crewed glider; 1891 Lilienthal's gliders; 1903 the Wright Flyer at Kitty Hawk (12 seconds, 120 feet); 1909 Blériot crosses the English Channel; 1919 Alcock and Brown make the first non-stop transatlantic flight; 1927 Lindbergh's solo transatlantic flight; 1932 Amelia Earhart's solo transatlantic flight; 1939 first jet-powered flight (Heinkel He 178); 1947 Chuck Yeager breaks the sound barrier in the Bell X-1; 1957 Sputnik 1; 1961 Yuri Gagarin orbits Earth; 1969 Apollo 11 lands on the Moon. Each milestone has an elegant SVG line illustration of the craft, its date and a short caption. Parallax clouds at several depths; a small paper plane travels along the timeline. Clicking a milestone expands its card. A progress altimeter shows the year. Typography: an aviation-inspired sans with serif captions. SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
