Interface Alternatives mandatory: Removed none option from interface: field in spec-product frontmatter. Interface now always runs, even in Auto/Light mode. The skill covers system interfaces too (API contracts, auth flows, data layer patterns), not just visual UI.
Auto-chaining simplified: "Shape Up" now always includes Interface, eliminating the separate "Shape Up + Interface" option. Auto/Light mode no longer delegates the interface decision to the LLM — standard is fixed.
