Document the static Python course and Pages site

[khlaifiabilel]

Summary

• describe the eight static slide decks and legacy chatbot shell without claiming an installable expert-level course
• use the current repository and working Pages identities and document the stale in-page historical identity
• record external-asset, workflow, provenance, maintenance, and license limitations

Verification

• git diff --check
• node --check assets/js/script.js
• current Pages URL returns HTTP 200
• no dependency installation required; the Jekyll workflow was not run because it uses a floating legacy container
