Replaces the manually-positioned wokwi-element mock (CircuitPreview) in
the /examples gallery with real screenshots of the actual simulator
canvas, so each card shows the example's boards + components + wires
exactly as they appear when you open the example.
How it works
- A new <ExampleThumbnail> component tries
/examples-thumbs/<id>.{webp,png} first. If the image 404s — or no
thumbnail has been captured yet — it falls back to the existing
CircuitPreview component. No-op for examples without a screenshot.
- ExamplesGallery and ExampleDetailPage now render <ExampleThumbnail>
instead of CircuitPreview directly.
- Explicit example.thumbnail field still wins (kept the existing
override path in case someone wants a custom asset).
Capture pipeline
- Generated by velxio-prod's scripts/capture-example-thumbs.mjs
(Playwright + sharp). For each example: opens /examples/<slug>,
clicks "Open in Simulator", waits for [data-board-id] elements,
computes the bbox of all boards + components, sets a transform on
.canvas-world to center and fit them with 12% padding inside the
canvas viewport, screenshots .canvas-content, and re-encodes to
600x360 @2x DPI as .png + .webp.
This commit ships the first batch (102 of ~129 examples — the rest
will follow once the capture completes; missing slugs gracefully
fall back to CircuitPreview in the meantime).
