Write Hugo Twin Content

Use this skill when new or updated articles must land in one of the two Hugo sites whose content roots are fixed below.

Content Roots

Site	Content path (relative to workspace root)	Public site (from `hugo.toml`)
Authority Blog (portfolio / blog)	`authority-blog/content`	`https://authority-blog.example.com/`
Learn (notes / research)	`learn/content`	`https://learn.authority-blog.example.com/`

Both sites use the PaperMod theme, Vietnamese or English copy is acceptable when it matches sibling pages in the same folder.

Flagship topics ship twice: Vietnamese twin on learn, expanded English masterclass on authority-blog.
Only learn links up to authority-blog (one-way authority flow). authority-blog never links to learn.authority-blog.example.com.
Corpus indexes: learn/plan/CONTENT_INDEX.md and authority-blog/reports/CONTENT_INDEX.md — refresh them when adding posts or series.
