16	* Reusable converter for border-radius (Union(Border_Radius \| Size)). One instance per property.
17	* Delegates tokenizing/expansion to Box_Shorthand_Parser; a null parse declines (-> custom_css).
18	*
19	* A single token emits the Size member. Two-to-four tokens expand via the CSS corner rule
20	* (top-left/top-right/bottom-right/bottom-left) and map physical->logical (TL=start-start,
21	* TR=start-end, BR=end-end, BL=end-start) into a Border_Radius PropValue. Elliptical values (a "/"
22	* separating horizontal/vertical radii) cannot be modeled by the single-Size-per-corner shape, so
23	* they decline to custom_css — the parser already rejects the "/" form while keeping calc() division
24	* (a single paren-wrapped token) convertible.
