/**
 * Workflow Verification: RoiTimelineChart
 * Session: cec0b057-7e04-413e-a4ae-eab672d78d3d
 *
 * Golden path and sad-path exercise for:
 *   - resources/js/Components/Roi/RoiTimelineChart.tsx
 *
 * Scope derived from diff (no SUCCESS_CRITERIA / WORKFLOW_BLAST_RADIUS files present).
 *
 * === Workflows verified ===
 * A. Empty state (no tracked data): ROI Dashboard renders the zero-state
 *    correctly — no console errors, no blank page.
 * B. With-data state: ROI timeline chart renders with "Avg Daily Click Lift"
 *    column label in the accessible ChartDataTable companion. The "Show data table"
 *    toggle reveals the column header.
 * C. ROI dashboard loads without console errors (loading / error free)
 * D. Permission denied: unauthenticated access redirects to /login.
 *
 * === Architecture notes ===
 * - The ROI Dashboard (/sites/{site}/roi) renders RoiTimelineChart only when
 *   summary.total_recommendations_tracked > 0 (has-data branch).
 * - timeline_data is populated only when snapshots exist with
 *   days_tracked >= interval AND is_significant = true.
 * - To test chart branch: seed a RecommendationRoiSnapshot with correct schema
 *   (see factory: baseline_date, baseline_clicks, current_clicks, days_tracked, etc.)
 *
 * === Test isolation ===
 * Tests B/C seed snapshots in beforeEach/afterEach to ensure isolation.
 * Tests run with fullyParallel=true across desktop/tablet/mobile projects.
 * Seed state is scoped to the E2E test site (siteId from .seed-data.json).
 *
 * === public_id routing ===
 * Site model uses HasPublicId — URL uses ULID (public_id), not integer PK.
