• Version Badge: Auto-updating version badge in site navbar, refreshed on every release via CI

📖 Content Improvements

• Progressive Disclosure: Enforced scaffolding across 9 modules — solution blocks decomposed for pedagogical consistency
• Function Decomposition: Standardized naming conventions and formatting across all 20 modules
• Module 15 (Quantization): Corrected INT8 zero-point values in quantization docs
• Module 16 (Compression): Fixed sparsity percentage bugs
• Module 19 (Benchmarking): Aligned MLPerf box-drawing characters and tree indentation
• EmbeddingBackward: Moved from Module 06 to Module 11 where it belongs conceptually

🐛 Bug Fixes

• SocratiQ Typo: Fixed typo in SocratiQ introduction by @BunningsWarehouseOfficial in #1170
• Google Auth iframe: Fixed Google auth and slow index.html loading by @kai4avaya in #1172
• Notebook Filenames: Aligned notebook filenames with Tito convention across all docs (fixes #1176 — thanks @sotoblanco)
• Missing Exports: Added missing #| export directives across 10 modules
• PDF Build: Capped Mermaid figure sizes and fixed nested code fences for LaTeX output
• VS Code Extension: Fixed notebooks opening in raw JSON instead of interactive editor

📚 Documentation

• Updated TITO reference docs to match actual CLI commands
• Fixed broken paths in CONTRIBUTING.md and INSTRUCTOR.md
• Added intra-module scaffolding subsection to progressive disclosure paper
