+     wet black paint, PURE CSS (the SVG text filter embosses badly on a
+     disc; headless A/B renders picked this). Borderless per operator:
+     the painted disc IS the badge. Layers: warm ambient top sheen, wet
+     lower reflection arc, bottom depth vignette, paint-black base; inset
+     rim lights; and a curved liquid "window streak" on ::before (under
+     the badge's z-1 content, above the paint). Revert: delete this block. */
