Course Content Authoring

Schema authority: all primitive field names (unit / concept / prompt / task / material / quiz / faq / illustration) come from _shared/domain-primitives.md. When this skill mentions a field, that file is the source of truth.

Filename convention (English-first): all generated files and directories use English names. The mapping from legacy Chinese names is in _shared/domain-primitives.md §0.

This skill produces the teaching substance of a course: the things a learner reads, copies, listens to, or works through. It anchors every artifact to the outline IDs from course-outline-design, so the next stage (SPA conversion) can wire them up mechanically.
