/**
 * Gerber Viewer (gerbview) WASM E2E Tests
 *
 * gerbview is its own standalone kiface (FRAME_GERBER), launched via single_top
 * like pcbnew/pl_editor. gerbview.html seeds a default KiCad config in preRun, so
 * the shared first-run setup wizard never opens — the viewer comes straight up.
 * Scope is launch-only: the viewer must start, paint a canvas + toolbars (incl. the
 * layers manager), populate the element registry, and produce no WASM abort.
 * Loading actual Gerber files is out of scope here.
 *
 * Determinism: no waitForTimeout, no wizard click-through loop, screenshots via
 * stableShot (stabilizes before comparing).
