Plan step 36. The old `state-layer` utility hid its layer on `[aria-disabled='true']`; the menu item's hand-written layer dropped that, so a disabled item, which stays focusable, drew the 10% focus layer. Its 38% ink now reads --md-sys-state-disabled-content-opacity, as button.css does, instead of a literal.
