I opened Wonder just to nail the look because i had this film-darkroom idea stuck in my head, warm safelight glow, trays that feel recessed, one ember accent carrying the whole thing, and I wanted to see it before building anything. What got me was how much "just messing with the look" turned into. It didn't feel like i was wrestling a canvas, wonder held all of it as decisions, not some flat screenshot I'd have to reverse-engineer later. So my whole process flipped. Instead of building a mockup and then rebuilding it for real, I hooked Wonder up to Claude Code through its MCP feature and turned the design straight into an actual working web app: darkroom-two.vercel.app here's my wonder file; take a look:Wonder file
