 * Captures ≥5 1440x900 snapshots covering the brief's deliverables:
 *   - LogViewer renders with ANSI colors visible
 *   - LogViewer search box opens
 *   - ExecPanel idle state with Open Shell button
 *   - ExecPanel iframe loaded after click
 *   - ExecPanel fallback when iframe blocked (forced via timeout)
 *   - SessionsPage list view
 *   - SessionsPage filter panel
