  /*
    Step card carrying a narrative beat ("Phase One — Foundation"). Two stickies
    per step: a colored node sticky (Shrikhand phase title + Caveat phase label)
    and a white-bordered content sticky (Zilla Slab body copy). Designed to be
    used in a vertical stack of 3-5 steps; adjacent steps should swap node-color
    and alternate tilt direction.

    The original template ships a dashed-bezier SVG connector between node and
    body. That rail is dropped from this preset per §8.3 (UI chrome — no
    scene-level use); add it back in scene HTML if needed.
