+## How it works
+
+The illustrations below show alternative capture arrangements and a proposed operator interface. They are AI-generated concept illustrations, not installation drawings, real defect evidence or screenshots of implemented software. Geometry and defect appearance are illustrative and not to scale. Teal cones represent camera fields of view; amber rays represent illumination.
+
+### 1. Complementary views of the same surface
+
+![Two cameras view the same membrane surface: an overhead view with diffuse light and an oblique view with low grazing illumination.](docs/images/complementary-views.png)
+
+Camera A observes the surface approximately perpendicular to the web; camera B adds an oblique view. Diffuse light reveals surface appearance, while grazing light can make raised features visible through highlights and shadows. Both views target the same inspection region. In experiments, switch lighting recipes separately when needed to distinguish their effects; the drawing shows the available sources together.
+
+### 2. An alternative: inspect both surfaces
+
+![One camera and light above the membrane and another camera and light below inspect opposite surfaces across an open span between rollers.](docs/images/both-surfaces.png)
+
+If both surfaces matter, place one camera and a suitable light on each side of an unobstructed span. Each camera inspects its own surface. This is an alternative to the complementary-view arrangement, not a requirement for four cameras. Mechanical clearance, coverage and triggering still need to be established.
+
+### 3. Detect, highlight and review
+
+![Illustrated monitor showing two membrane images, a red suspected-defect region and human review controls.](docs/images/inspection-monitor.png)
+
+The proposed interface displays the latest captures and highlights a suspected defect on the matching image. The operator confirms or rejects the suggestion; the catalogue retains the image evidence and review history. Optional generated descriptions arrive later and do not delay the alarm. The illustrated monitor shows the complementary-view scenario above; it does not demonstrate detection accuracy.
