Open with the project links and a feature list checked against the app,
list the downloads per platform, document link imports and Android
automation, and describe what a source build needs today. The Linux
note now names the runtime tray library and applies only to the
AppImage and .rpm, since the .deb declares its dependencies, and the
Android build no longer asks for an ANDROID_NDK variable.
The preview mockups keep their frames and now show the current UI: the
sidebar, the reworked dashboard and the floating dock.
