Motion authoring — from measured manifest to real motion

Runs only when the user chose a converted project and authored motion. The generator gives you structure, inert skeleton mounts, and motion.manifest.json (measured triggers, pageTriggers, initial-hidden hints). Authoring is the step where those mounts become real motion and the build is proven against the reference. This is the N2 dogfood recipe (nesil: one 31.21 s master scrub, exact 25,650 px parity).

Profile note: this skill's tools are analyze_page_structure, analyze_scroll_map, build_motion_manifest and retained build_project. Examples below use 1.x names (default full). On AWWWARDS_MCP_PROFILE=v2, use inspect_page {request:{kind:"structure", url}}, analyze_motion {request:{kind:"scroll", url, compact:false}} and build_motion {request:{kind:"manifest", bands, scrollCensus}}; build_project stays flat. The census must be compact:false — a compact census has no anims[] and cannot feed build_motion. Full mapping: v2-routing.md.
