                The generator assembles a standards-based web app manifest from your
                details, omitting empty optional fields so the JSON stays clean. It
                validates URLs, hex colors, icon sizes and purposes, then flags the
                things browsers look for when deciding whether your site is
                installable. The manifest, the preview and the checks are produced
                entirely in your browser.
