I built a tool that turns one prompt into an animated promo video for about 13 cents of compute. Feedback welcome

Small businesses post promos all the time: prices, openings, new menus. AI footage tools are expensive per clip, and you can't fix one wrong price without regenerating the whole thing. So I made the video out of code instead. Claude writes the animation (HTML + GSAP), and my VPS renders it. Changing a price is a small edit and a re-render. The numbers so far: * About $0.13 per 15s video in model calls, and $0 per render on a small VPS. * About 3 minutes from prompt to MP4, including an automatic review-and-fix pass. * Edits cost about $0.02 and take a couple of minutes. * Square, vertical or wide, 5-30 seconds, with the business's real logo. What doesn't work yet: no music or voiceover (it's coming) Would you use this for your own launches, or does it need sound first?
