The prompt

Split Flap Board: A departure-board display of split-flap characters in six rows. Rows update every few seconds with invented destinations and times, each flap flipping with a 3D animation through intermediate letters and a synthesised clatter. A text box lets the user push a custom message. 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.
