Small-size readability

• Contrast: white mark on orange fill — check both dim OLED and bright LCD.
• Silhouette budget: rounded square, qr code should remain readable after the store’s rounded-square crop.
• detailed/illustration detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.4/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing QR コード読み取りアプリ－バーコードリーダー・QR Now, not authoritative store scores.

Transferable design moves

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