Usage

When adding a new experiment:

  1. Choose at least one Primary Tag (Domain or Type).

  2. Choose one or more Secondary Tags (Topics & Methods).

  3. Add them to the **Tags:** line in your .md file.

  4. Update the Experiments Gallery using the corresponding CSS classes (tag-primary for primary tags, tag-secondary for secondary tags).
