### Pre-Filled Template & Production Source

```md
A wide, flat-lay photograph of a large handmade cyanotype print lying on a weathered pale oak worktable, the print filling most of the frame. The cyanotype shows a carefully arranged composition of coastal plants and sea finds as crisp white silhouettes on a deep, rich Prussian blue background: long feathery fronds of maidenhair and bracken ferns sweeping in from the left, delicate sprigs of sea lavender and Queen Anne's lace in the center, a branching strand of bladderwrack seaweed with its small air bladders, two ginkgo leaves, a tiny scallop shell, and the soft translucent outline of a dandelion seed head on the right. Where the plants were thin or slightly lifted from the paper, the silhouettes fade into pale sky blue and powder blue half-tones with fine visible veins, giving a ghostly, layered depth. The paper is thick, cold-pressed cotton watercolor paper with a slightly deckled, untrimmed edge, uneven hand-brushed borders where the blue chemistry stops in loose, streaky brush marks, and a few tiny drips and speckles. Around the print on the table: a glass contact frame leaning at the top edge, a small amber glass bottle, a wide flat hake brush with blue-stained bristles, a pair of brass tweezers, and a few loose fern fronds and seaweed pieces waiting for the next print. Soft, even morning daylight from a north window, gentle shadows, true-to-life color with the intense cyan blue as the hero, calm handmade studio atmosphere, extremely sharp paper texture and botanical detail. Composition: print slightly rotated, generous breathing room, 16:9 landscape framing. No people, no hands, no text, no labels, no signature, no watermark.
