/* Smooth corner curvature for every rounded surface. Inside the support
 * guard, all corners curve along superellipse(1.5) — between a circular arc
 * (round = superellipse(1)) and a squircle (superellipse(2)) — instead of the
 * default arc; engines without corner-shape keep circular corners because the
 * token and the rule exist only inside the guard.
 *
 * corner-shape does not inherit, so the universal selector applies the token
 * to elements and their ::before/::after; other pseudo-elements (for example
 * the ::-webkit-scrollbar parts) stay circular.
 *
 * Full-round shapes opt out where they are declared: a superellipse deforms a
 * circle into a squircle and squares off capsule ends, so every effectively
 * uncapped radius (50%, 100%, or a pill radius far above the box size) pairs
 * `corner-shape: round` with its `border-radius` in the owning component
 * sheet. The corner-shape stylesheet spec enforces that pairing. */
