API/Database issue: features/shapes-and-graphics - blend_modes results not shown

The first block in the Shapes & Graphics section is showing the following error message, along with a `debug` caption, instead of the results themselves:

`No available data for block blend_modes | path(s): dataAPI.surveys.state_of_css.css2023.shapes_graphics.blend_modes | type: ToolFeatureExperienceBlock`


The issue identifies the Shapes & Graphics section, the blend_modes block, and the dataAPI.surveys.state_of_css.css2023.shapes_graphics.blend_modes path, but names no source file or test. Trace that data path first and compare it with the other blocks in the section; done means the block displays its results instead of the no-data debug message.
