Build a Safari extension for iPhone/iPad that creates a calm, private reading experience. It should block ads and trackers with rule lists that can be updated from our server, provide an on-demand Reader view that extracts the main article and renders it in a clean, customizable layout (fonts, themes, spacing), and translate text in place via a remote service without reloading the page. Keep everything fast and lightweight so there’s no visible lag, and include per-site controls with an easy way to turn features on or off.
