/**
 * Spike test: load real .kicad_pcb demos through pcbnew's File → Open.
 *
 * Flow (parametrized for each demo below):
 *   1. Wait for pcbnew to come up (dismiss the first-run KiCad Setup wizard
 *      if it appears — depends on whether MEMFS already has config).
 *   2. Inject the demo's .kicad_pcb (+ .kicad_pro for completeness) into
 *      MEMFS at PATHS::GetDefaultUserProjectsPath() — confirmed by
 *      load-pcb-probe.spec.ts to be /home/kicad/documents/kicad/10.0/projects/.
 *   3. Drive File → Open via menu helpers.
 *   4. Click on the file row in wxFileListCtrl (wasm port doesn't register
 *      listctrl rows in wxElementRegistry, so we click by the filelist's
 *      bounding box), then focus the filename text input and press Enter to
 *      trigger wxGenericFileDialog's accept path. (A direct OK button click
 *      doesn't dismiss the dialog in the wasm port; the listctrl row click
 *      populates the text input but doesn't mark the row selected enough for
 *      OK to satisfy validation.)
 *   5. Dismiss any post-load info dialogs (missing-libs etc. — pic_programmer
 *      uses local footprint libs and may pop one of these).
 *   6. Wait until the file dialog and the LoadBoard progress dialog both go
 *      away. Screenshot the loaded board, named per-demo.
 *
 * The board load itself was crashing in `Classify` inside `rtree.h` until we
 * fixed the wasm-only `ELEMTYPEREAL = intptr_t` (32-bit on wasm32) typo at
 * `kicad/libs/kimath/src/geometry/shape_poly_set.cpp:1927`. See
 * `features/<branch>/rtree-debug-findings.md` for the full trail.
