Show HN: I vibe-coded a times table app for my kid (rainbow-math-grid-fun.lovable.app)

My kid is learning his times table. Between my work (which is more managerial these days) and family, I don't get a lot of focus-time I can spend writing code, so I decided to give this "vibe-coding" thing a try. An hour later, I had this game, which he's had a lot of fun playing.
