Our Commentary ​

Oh, this is a pain point I know all too well. That Property 'startViewTransition' does not exist error is just one of many. It's a constant battle to keep TypeScript definitions aligned with the bleeding edge of browser APIs. I genuinely wonder if there's a more proactive solution here, maybe something built into the browser spec process itself, to generate types. It's a small friction, but it adds up.
