Build System Improvements and Font Fallback Issues

[nipunbatra]

Font Loading Issues

• XeLaTeX builds sometimes fail when specific fonts (Inter, Roboto, Fira Sans) are not available
• Font fallback chain implemented but could be more robust

Build System Enhancements Needed

• Progress reporting is working well but could be enhanced with time estimates
• Error handling could be improved for partial build failures
• Consider parallel compilation for faster builds

Typography and Styling Issues

• Some confusion matrix colors could be more accessible
• Footer positioning works but could be fine-tuned
• Table of contents bullets styling could be improved

Files Affected

• (font handling)
• All Makefiles (build system)
• (progress reporting)

Priority

Low - these are enhancements rather than blocking issues
