Small-size readability

• Contrast: white mark on black fill — check both dim OLED and bright LCD.
• Silhouette budget: alarm clock, bell, handle, knob, feet, dial 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 イヤホン時のみアラーム, not authoritative store scores.

Transferable design moves

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