Small-size readability

• Contrast: black mark on black fill — check both dim OLED and bright LCD.
• Silhouette budget: piano keys should remain readable after the store’s rounded-square crop.
• Internal usability score for this capture: 0.2/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing ピアノ -シンプルなピアノ- 広告無し, not authoritative store scores.

Transferable design moves

• Keep piano keys as the primary silhouette before adding secondary ornaments.
• If the fill stays black, push identity into a single geometric mass rather than a busy texture.
• This capture’s monochrome/detailed vocabulary transfers best when the same restraint is applied at export size.
