✅ E2E Coverage — No Issues

Changed files:

• app/platform/[tenant]/course-content/[course_id]/__tests__/layout.test.tsx
• app/platform/[tenant]/course-content/[course_id]/layout.tsx
• components/edx-iframe/__tests__/edx-iframe.test.tsx
• components/edx-iframe/edx-iframe.tsx
• components/ui/__tests__/popover.test.tsx
• components/ui/popover.tsx

No new page.tsx routes were added. Coverage files (e2e/coverage.json, e2e/COVERAGE.md) are unchanged — no regression detected.

Decision: CASE E — No new app routes were introduced. All existing coverage is intact.

Note: The gh pr review --approve command requires explicit tool approval in this environment. A formal GitHub review approval could not be posted, but coverage analysis confirms no issues with this PR.
