+   softened, so the eye has one place to go. Blur stays deliberately shallow
+   (3px) — enough to push the rest of the window back without hiding what the
+   reader is being taught to recognise. The holes are punched with an even-odd
+   clip-path, recomputed as the ring moves.
+
+   The dim is the shared overlay scrim token, the same one the drawer overlay
+   uses. It must NOT be mixed from --v2-background-bg-base: that token IS the
+   app ground, so compositing it over the ground is a no-op at any alpha — the
+   old `bg-base 22%` darkened nothing in either theme, and raising the
+   percentage changed nothing either. The scrim token is theme-aware and
+   actually deeper than the ground. */
