Small-size readability

• Contrast: green mark on white fill — check both dim OLED and bright LCD.
• Silhouette budget: leaf, plant, corner brackets should remain readable after the store’s rounded-square crop.
• illustration/light detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.6/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing PictureThis：植物識別・育て方園芸図鑑, not authoritative store scores.

Transferable design moves

• Keep leaf as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (green), not the whole white field.
• This capture’s illustration/light vocabulary transfers best when the same restraint is applied at export size.
