ATTR.2 SuperCad Studio: tick what goes in the Finalize and export zip

Owner 2026-11-03. The export dialog has a 'Project documents in the zip' list under the formats: Project file, Notes, Tasks, Time log, Calendar events, Project report binder, Credits page, Documentation folder. Plugins offer items through api.exportItem. The binder is ticked the first time, the rest are not; ticks are remembered in this browser. They go in documents/ and contents.txt names anything that had nothing to add. CC0 items stay on the credits page. Tests: bin/test-super-binder.mjs, tools/super-test/binder.mjs. In /lab, not released.
