*
* JIRA: RECIPE-0006
*
* NOTE: This test is SKIPPED in favor of fast unit tests in
* instagram-caption-extraction.unit.spec.ts
* CURRENT STATUS: Instagram actively prevents web scraping.
* - All extraction methods (JSON, DOM, Internal State) return only truncated text (≤130 chars)
* - Full captions are loaded dynamically via GraphQL after user interaction
* - "More" button expansion requires complex interaction simulation
*
* This test requires:
* - Real Instagram page loading (slow, 30s timeout)
* - Playwright browser automation (flaky in CI)
* - Live Instagram URL (may change over time)
* This test validates that:
* 1. Multiple extraction strategies are attempted
* 2. The test fails if ALL strategies produce truncated output
* 3. Anti-scraping detection is working
*
* Use this test manually for validation against real Instagram data:
* npm test -- instagram-caption-extraction.e2e --run
* To get full captions, consider:
* - Official Instagram Graph API (requires authentication)
* - Manual user flow simulation with authenticated browser
* - Alternative data sources
