/**
 * CMD+K API SCROLL POSITION TEST
 * ==============================
 * Tests the /api/cmd-k endpoint integration with ninja-keys command palette.
 *
 * Tests:
 * 1. API returns valid JSON with experiences, projects, courses
 * 2. ninja-keys receives data from API (not hardcoded)
 * 3. Scroll navigation works for dynamic entries:
 *    - Experience items (e.g., Olympic Broadcasting)
 *    - Project items (e.g., Somos Una Ola)
 *    - Course items (e.g., Codecademy Certifications)
 * 4. Static navigation actions still work (e.g., Skills section)
 *
 * Related: doc/16-CMD-K-API.md
