The "Repository Structure" block was hard-wrapped by the AsciiDoc→Markdown conversion, so the entire tree collapsed into a single paragraph and rendered as one run-on line.

Rebuilt from the block's own content:

• depth recovered from the │ continuation bars that survived the wrap
• the guide entry moved under .github/, where the guide actually lives
• \# escapes unescaped, └── restored on the last entry of each group
• the block fenced with ```text so it renders as a tree

Every annotation ("Perimeter 1-2" etc.) is preserved — nothing invented, nothing dropped.
