style.layout-surface (issue #387): the shape a container’s direct children are projected onto at paint time, plus the one perspective and turntable rotation shared by all of them. radius/arc-x/arc-y are pixels/degrees, not Lengths — this bends a fixed layout, it does not participate in it.

Cylinder only curves around its arc-x (a horizontal wrap, like a scroll); a child’s vertical position is left exactly where taffy put it. Sphere curves around both arc-x and arc-y, which is what a dome needs. Neither closes into a full globe — arc-x/arc-y describe a patch, typically well under 360°; wrapping dot data onto an actual closed globe is dot_map’s projection: "orthographic" instead (a different problem: culling a far hemisphere, not bending a flat grid).

Depth ordering. Children are painted in the same declaration/z-index order as a flat container — a cell that curves behind another one does not sort behind it. For an arc-x/arc-y patch well under 180° (the intended use: a dome of cards, not a fully enclosing sphere) every child still faces the camera, so this is not visible; a wide enough arc or enough rotate-y to turn cells past the limb can make a far cell paint over a near one. Tracked generally by #93, not solved here.

Variants

Cylinder

Fields

radius: f32

Cylinder radius in pixels.

arc_x: f32

Total angular sweep across the container’s width, in degrees.

perspective: Option<f32>

rotate_x: Option<SurfaceAngle>

rotate_y: Option<SurfaceAngle>

Sphere

Fields

radius: f32

Sphere radius in pixels.

arc_x: f32

Total angular sweep across the container’s width, in degrees.

arc_y: f32

Total angular sweep across the container’s height, in degrees.

perspective: Option<f32>

Shared vanishing-point distance in pixels, None = orthographic (curved, but no foreshortening).
