Execute Phase 1 and Phase 2. Phase 1: Your syllabus PDF has been downloaded and converted to text at `../../../../scratch/DI04000101.txt`. Extract teaching scheme and course content, and update your `DI04000101.json`. Use `../../../../11-ec/sem-3/DI03011011/DI03011011.json` as schema reference. Phase 2: Create lecture-wise JSON plans in `beamer/lecture-plans/`. Use `../../../../11-ec/sem-3/DI03011011/beamer/lecture-plans/` as the exact lecture schema. Report back here when both phases are complete.
