Kenneth-Cho-InfoSec/Solipsism ? reverse-engineered prompt

Build me an Android browser app that feels built for one handed use, with the main controls in a slim rail on the left or right and the webpage taking up most of the screen.

I want it to open websites in a WebView, support tabs, bookmarks, history, downloads, search, QR scanning, share, find in page, fullscreen video, and a quick screenshot action. Add solid privacy tools too, like ad and tracker blocking, custom filter rules, per site permissions, and options for blocking risky downloads with a simple malware scanner. Include a decoy mode, userscript support for Tampermonkey style scripts, and a way to customize which actions live in the rail versus the overflow menu.

Make the UI feel modern and polished with Material 3 expressive styling, themes, accent colors, compact layouts, and accessibility friendly controls. Keep it fast, clean, and easy to use with one hand. If you need to check current Android or WebView docs online while building it, go ahead.
