Forbidden:
  A drop shadow on every card, or several shadow sizes with no rule governing which means what

Instead:
  `--shadow-surface` is `none` in all three modes. Depth comes from `--color-stroke-weak` or a surface-colour step. `--shadow-raised` exists for exactly two cases: overlays — dialogs, popovers, dropdowns — and sticky navigation in `editorial`, which must read as above the content scrolling beneath it.
