No PWA manifest file detected

A Progressive Web App (PWA) manifest is a small configuration file that tells browsers how to install your website as an app on a phone or desktop, including its icon, name, and colour scheme. No manifest was found. Mobile browsers show "Install this app" prompts to visitors when a site has a manifest and meets basic criteria. Without one, you miss a low-cost acquisition channel — installed web apps get regular home-screen visibility just like native apps. Ask your developer to create a manifest.json file with your app's name, icon, and brand colours and link it from your HTML. This takes an hour or two and unlocks the browser install prompt on all major platforms.
