Check (iii) flagged two shapes the package's own stylesheets (and their
stylesheet tests) already treat as fine: `linear`, M3's own easing for
continuous motion (an indeterminate progress indicator's rotation), and a
box-shadow that is only an inset or outline-style ring — `[inset] 0 0 0
<n>px` in a `var(--md-sys-color-*)` role, or one `color-mix()`-dimmed for a
disabled ring — the shape a focused field's edge or a day's "current"
outline draws. A blurred shadow or one with a literal colour is still
reported.
