Output format

Default output is .sunset/output/ beneath the parsed root. index.md contains project frontmatter and a file table. Per-file output is written to files/<sanitized-relative-path>.md; path separators become underscores.

Every per-file document starts with YAML frontmatter:

---
file: main.go
language: go
package: main
lines: 28
function_count: 2
type_count: 0
import_count: 3
tags:
  - has-functions
---

Summary mode renders extracted functions, types, imports, and documentation where supported. parse --detail full instead renders a concrete syntax tree. update always writes summary output.
