Module 10's lab embedded literal `/path/to/` placeholders and a first-use `git apply` with no explanation, unlike the Module 1 exemplar. This adds the course-wide "use your real course path in place of /path/to/" gloss (matching M04/M07/M26), a half-sentence gloss on git apply, and a note that review-lab is a throwaway repo separate from tasks-app. Closes #53 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CfDmDAQL7xuSRm2L4qApvn
