GTK's -gtk-recolor proved too fragile across different contexts, failing to substitute the foreground color even when the SVG path used #000000. Instead, we now generate two statically colored SVGs (normal + hover) directly from the Nix palette hex codes, bypassing GTK's SVG recoloring engine entirely.
