+## Automated smoke results (2026-07-05, Chromium via Playwright)
+Several checklist items above were verified programmatically post-merge (forcing
+`is-loading` on `#cld-network` and reading computed styles / geometry):
+
+- **Spinner shows + clears (both apps)** — PASS. SESPy CLD + MosaicSES Topology:
+  `::before` content `"Rendering network…"`, and geometry `outputCoversCanvas: true`
+  (output box == canvas box, 582×650 SESPy / 474×650 MosaicSES) — veil fully
+  covers the canvas; pseudo-elements paint above it.
+- **MosaicSES separate skin got the CSS** — PASS. `::before` resolves in the
+  MosaicSES app (proves its own `www/sespy-skin.css` copy carries the block).
+- **Reduced motion** — PASS. Under `prefers-reduced-motion: reduce`, `::after`
+  `animation-name: none` (no rotation); veil + label still shown.
+- **Modal z-order** — PASS. Spinner `::before`=5 / `::after`=6 vs the fork's
+  `.pyvis-modal-overlay`=1000 — modals paint above the spinner.
+- **Dark theme (deep-ocean)** — PASS (legible). Body bg `rgb(11,31,51)`; the pyvis
+  canvas stays light in every theme, so the white veil (68%) + dark label
+  `rgb(29,31,33)` are high-contrast and consistent — no jarring flash.
+
+Still needs a human eye (interaction-dependent, not auto-verified): Leverage
+physics-on re-show, MosaicSES compartment drill-in, an actual node/edge modal
+click over a just-loaded graph.
