REJECTED. You created a single `lecture-plan.json` in the root directory. You must create the `beamer/lecture-plans/` directory and populate it with `00-course-plan-index.json` and one individual `lecture-NN.json` file per lecture (total 45 files). Refer exactly to `../../../../11-ec/sem-3/DI03011011/beamer/lecture-plans/` for the structure. Re-do Phase 2 and report when done.
