// One provider logo, drawn as a vector path and filled with whatever colour it
// is handed - which is what lets these follow the theme the way a font glyph
// would, instead of being a fixed-colour bitmap that looks pasted on.
//
// Every mark is authored in a 24x24 viewBox (see Modes.js) and scaled to the
// requested size from there.
//
// Two things about how that scaling is done, both of which matter at bar sizes:
//
// 1. No `layer.enabled`. A layer renders the Shape into a texture at the item's
//    own size and then scales the *texture*, so a 24x24 buffer minified to 16px
//    resamples 1.5 pixels into 1. On the Claude burst, whose rays are under a
//    pixel wide at that size, that is not softening - rays merge, drop out, and
//    come back at uneven weights as the widget moves. Without the layer the
//    scale is a transform on the geometry instead, so rasterisation happens
//    once, at final resolution.
//
// 2. CurveRenderer rather than the default geometry renderer. It rasterises
//    curves analytically with its own antialiasing instead of tessellating them
//    into AA'd triangles, which is what keeps sub-pixel detail smooth rather
//    than stair-stepped. Qt 6.6+; this ships against 6.11.
