Instagram truncates captions and changes class names with every deployment. Semantic DOM searches and a MutationObserver still load the full text reliably.

Nine TypeScript errors at once, all about missing .js extensions in imports. The cause is a tsconfig.json setting that is correct for Node.js but incompatible with Vite as a bundler. I explain why and show the right configuration.
