Coincidentally, so is good web design.
One thing that really really annoys me about LLM-generated websites is that they have entrenched, without good reason, --webkit-font-smoothing: antialiased.
Also Claude, having evidently been tested by people exclusively under the age of 25, routinely chooses smaller font sizes and lower text contrast than makes any kind of sense.
Also the control could just be a slider. Much easier and simpler on all platforms.
Nice idea though.
