+
+Made from the earth picture so the soil matches: `fal-ai/nano-banana-pro/edit` with
+`earth-raw.png` as the reference image (`aspect_ratio: 1:1`, `resolution: 1K`, one image each).
+The prompt template, `{ore}` per kind:
+
+```text
+Keep this exact seamless tileable earth texture (same colours, same soil, same style, same top-down view) and embed {ore} scattered in the soil: about twelve separate lumps of different sizes, partly buried, spread evenly over the whole image including near the edges. No veins, no lines, no cracks filled with ore, no streaks - only separate lumps. The texture must stay seamless across all four edges. No text.

+- gold: `chunky nuggets of shining yellow gold`
+- silver: `chunky nuggets of bright shining silver ore`
+- ruby: `chunky raw red ruby crystals`
+- diamond: `chunky raw clear pale-blue diamond crystals`
+
+Gold has four variants (`--size 128` and `--size 256` like the others). Silver, ruby and diamond
+have two variants: one seamless tile for both (`--size 64 --colors 32 --band 8` and
+`--size 128 --colors 48 --band 14`), copied to `assets/textures/<name>.png` and `<name>-128.png`.
