## Context

- When loose material (rubble, dirt, ore) lies on top of or against solid rock, the two are hard to tell apart in the smooth look: the loose grains blend into the rock under them, so it's unclear where the solid ground starts and what is still to dig. The owner's screenshot: `/home/aaron/Pictures/Screenshots/Screenshot_20261024_214546.png` (a dug-out area around the bot where loose copper-coloured rubble covers the rock).

## Subtasks

- [ ] Find what makes them blend (similar colours, lighting, the smooth look's edge blending, no outline between loose and solid)
- [ ] Give loose grains and solid ground a clear visual difference (for example an edge or shading on solid rock, a different texture or brightness for loose grains), in both looks
- [ ] Check it in dark caves, under the bot's lamp, and with the thermal lens
