-New here? These images are generated with PIL — no download, no licence

-struggles and when to switch models. Click a button to load the image

+You don't need to come to this tab to use the samples — they're available as
+clickable thumbnails right under the uploader on the **🔬 Reconstruct** tab.
+Click one there and it loads instantly, no switching back and forth.

+This page just explains what each sample is for and how to read the results.
+The two are a deliberate side-by-side: **Sample 1** shows the model at its
+best, **Sample 2** shows where it struggles and when to switch models.

 ## How to Use This Application
 
-### First time? Use the sample tab
-Go to **🖼️ Try a Sample**, click **Load Sample 1**, then come back here
-and tick the consent box. You'll have a working reconstruction in under
-a minute without needing your own image.
+### First time? Use a sample
+On the **🔬 Reconstruct** tab, tick the consent box, then click one of the
+sample thumbnails under the uploader. It loads instantly — hit ▶ Reconstruct
+and you'll have a result in under a minute, no image of your own needed.
+(See the **🖼️ Sample Guide** tab for what each sample demonstrates.)
