// inline-block-layout.mms — inline-block formatting context demo (=^･ω･^=)
//
// One LayoutRoot. Three rows stacked block-style. Inside each row, an
// icon + a text run flow inline-block (icon left, text right). When a
// row's children are all inline-block, layout dispatches to the inline
// formatting context recursively.
//
// Topology:
//   LayoutRoot (block)
//     row1 T  + Style (default block — stacks under row0)
//       icon1 T  + Style{display:inline-block, w, h, margin-right}
//         R.circle2d
//       text1 T  + Style{display:inline-block, w, h}
//         Text { "..." }
//     row2 T (triangle)
//     row3 T (square)
//
// Glyph units everywhere; outer wrapper T.scale shrinks gu → world units.
