interactive skill-tree visual mockup — VibeSkill

Built and published a separate VibeSkill interaction mockup focused on layout experimentation rather than the main app flow. This sandbox tests whether category boxes should be draggable for layout tuning, how a hover-based expand control can fit the existing neural-map visual language, and how child branches should form around an expanded category while keeping connector geometry readable. The mockup stays close to the existing VibeSkill system but explores adaptive arc layouts, collision handling, core clearance, and highlighted parent-child expansion states as a distinct design track.
