/* Open DJ, TWO DECKS build: components.
   Compositing rule that every component below obeys:
   - Text and line work sit in an element with class .ink (mix-blend-mode: difference), so it inverts
     against whichever deck is behind it.
   - No ancestor of an .ink element may create a stacking context (no transform, opacity, filter,
     z-index, isolation or will-change on wrappers). A stacking context isolates the blend and the ink
     would vanish on the white deck. Motion is applied to the .ink element itself, never to a wrapper.
   - Opaque chrome (nav, dock, mobile menu) paints its own copy of the two decks (--deck-split) and
     blends its ink against that.
   - Illustration objects (.obj) use normal blending and stay the same dark object on both decks. */
