+### Texture sampling
+
+NETfishing artwork always uses nearest-neighbor sampling. Do not enable linear,
+bilinear, trilinear, or anisotropic texture filtering, and do not generate
+mipmaps. Shader samplers must declare `filter_nearest`. The
+`TextureSamplingPolicy` autoload applies nearest sampling to 2D canvas items,
+Sprite3D presentations, imported 3D materials, and dynamically constructed
+mesh materials at runtime.

+After importing new artwork, normalize its tracked import metadata where
+needed and run the focused policy check:
+
+```sh
+godot --headless --path . --script scripts/normalize_texture_imports.gd \
+  -- --apply --root res://path/to/new/artwork
+godot --headless --path . --script tests/texture_sampling_validation.gd
