Book Installer

Version: 1.0

Changelog

• v1.0 — First tracked version number for this skill. Adds references/mascot-placement-rules.md as the single canonical source for when and how often a learning mascot may appear, plus scripts/render-mascot-guide.py (renders those rules into a book's CONTENT-GENERATION-GUIDE.md between sentinel comments so the copy is regenerated, never hand-edited). The per-chapter ceiling is raised from 6 to 9 admonitions for longer chapters, and scripts/validate-chapter-mascots.py now reports the deprecated -encouraging spelling of the encourage pose class — which mascot.css never defined, so it rendered unstyled — and exempts the Chapter 1 self-introduction from the 1-3 sentence cap it always violated. Version is tracked under metadata: rather than a bare version: key, which strict packaging validation rejects.
