Notes and limitations
This is a high-fidelity mobile preview for web content with full touch support.
Touch emulation works for all content including cross-origin sites.
Screenshots work best for workspace HTML or same-origin content.
If a site refuses to load in an iframe (because of X-Frame-Options), open it in the browser or serve the project locally.
Vue and html2canvas are loaded from local files in media/vendor for offline use.
The CSP enables unsafe-eval for Vue template compilation.
