// The logo's alpha channel is the shape we want to render. Trim the source's
// own transparent margin first — logo.png carries ~15% baked-in padding, and
// without trimming that stacks on top of `pad` below, leaving the glyph at
// only ~half the icon's width. Trimming lets `pad` be the single source of
// padding so the shape actually fills the status-bar icon.
