/*
 * Scoped to the materials section and its image dialog.
 *
 * The operator, 12 October 2026, of this section: "currently looking too saturated". It was pink three times
 * over: a pink plaster photograph, a blush panel and a signature-pink bar, with berry numerals on top. It is the
 * section about silver, so it is silver now: a grey studio frame of the ring in water, the page's off-white
 * behind the words, charcoal type and hairlines, and berry kept for what can be pressed. The composition bar is
 * the two metals in their own colours, with no track behind them.
