Small-size readability

• Contrast: red mark on brown fill — check both dim OLED and bright LCD.
• Silhouette budget: folder, papers should remain readable after the store’s rounded-square crop.
• Lettering “invoices” must survive home-screen size; thin strokes usually fail first.
• detailed/illustration/photo 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 請求書, not authoritative store scores.

Transferable design moves

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