Markdown Package Opening Flow
Resolve the entry first, then generate a working document around the selection
1
Entry
Package-name Markdown first
Then README / index / main
Ambiguous: Document Chooser
2
Selection
Single: open directly
Multiple: order or path tree
3
Closure
Selected Markdown only
Direct resources only
Export paths stay self-contained
Supports the Package Capability Map chapter, not just an image rendering test.
