Original in-house MIT icons for WinPodX GUI controls; each asset is a 24x24 stroke-based SVG using currentColor so Qt can render a consistent themed icon set.

Exception: usb.svg is Bootstrap Icons' `usb-symbol`, used unmodified because the USB
trident has fixed official geometry that a hand-drawn approximation reads wrong at
icon sizes. Bootstrap Icons is MIT licensed (c) 2019-2024 The Bootstrap Authors --
