/**
 * UPLOAD DEEP — Comprehensive E2E tests for track upload flow.
 *
 * Scope:
 *  - Modal open/close behavior
 *  - File selection (input + drag-drop)
 *  - File validation (format, size, MIME type)
 *  - Metadata form
 *  - Upload progress indicator
 *  - Post-upload verification via API
 *
 * STRICT: every assertion must be real — no console.log fallbacks,
 * no silent catches. test.skip() only where a feature isn't implemented.
 *
 * Login: creator role (only creators can upload tracks).
 * Backend: POST /api/v1/tracks (multipart), GET /api/v1/tracks?user_id=X for verification.
