      "gold-balance",
      "Scientific-educational museum teaching illustration, wide landscape 3:2 composition. A simple unbranded traditional hand-held equal-arm beam balance suspended from its central cord, with two small shallow brass pans hanging level. In the left pan, a tiny folded paper packet holding fine gold-coloured dust; in the right pan, two small plain geometric cast-brass weights, clearly miniature. Balance on plain neutral warm beige tabletop; human hands only holding the suspension above, no full person, no royal identity or court symbols. A small lidded brass storage container blurred on the table at the edge, not focus. Meticulously readable functional reconstruction of weighing gold dust for an Akan history learning app, not a photograph of an authentic artefact, avoid sacred objects, invented proverbs, currency units, exact historical calibration, labels, words, letters, logos. Calm museum illustration with realistic materials and soft light, all cords connected plausibly, balanced beam and intact hanging pans. One single teaching image, no panels."

      "joining-strips",
      "Scientific-educational teaching illustration for a Ghanaian textile-history learning app, wide landscape 3:2. Close-up overhead view of two adult dark-skinned artisan hands stitching the long selvage edges of several narrow handwoven textile strips together on a work table. One hand guides a plain needle through adjoining edges, the other holds the woven strips aligned; a clearly visible simple connecting seam, separate unjoined woven strips beside it, thread and a small pair of scissors on the table. Simple original geometric stripes in ochre, indigo, cream and rust, woven texture visible, no asserted named traditional pattern, no adinkra symbols, no royal or sacred design, no named person. Make the distinction between a narrow woven strip and a larger assembled cloth immediately readable. Realistic educational reconstruction with soft natural light, not documentation of any particular Ghanaian weaver or historical workshop. No text, logos, labels, letters, or diagrams, no collage. One single teaching image."
