The prompt

Flappy Paper Plane: A paper plane glides through gaps between hanging paper streamers; click or space gives it a lift. It tilts with velocity, streamers scroll past with parallax clouds, and score increments per gap. Include a start screen, crash animation, best score in localStorage and gentle difficulty ramp. Build it as ONE self-contained HTML file: inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files); anything visual or audible is made in code (HTML/CSS, SVG, Canvas, WebGL or WebAudio). It must work when opened directly from disk, fit the browser window responsively, and run without console errors. Output ONLY the complete HTML file, starting with <!DOCTYPE html> and ending with </html>, with no explanation or markdown fences.
