Add Previous/Next navigation links to every chapter page Lets readers move sequentially through the 180-page tutorial without returning to Home.md each time. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TaBtmTnUHXgJEW18QsgiLk
Zero-pad chapter numbers to 3 digits (01 -> 001) GitHub's default wiki sidebar lists pages alphabetically since this wiki has no custom _Sidebar page. Mixed-width numbering (01..99 vs 100..180) sorted incorrectly as strings (e.g. "100" < "11"). Renaming chapters 1-99 to 001-099 fixes navigation order and keeps it consistent with the existing 100-180 files.
