表計算

Why this icon holds up

On 2026-08-13 the vault captured the 表計算 icon (Business, BR): 绿色圆角矩形文件背景，右上角有折角，左侧有白色字母X，右侧有白色横条。

No earlier vault capture exists yet, so this dated page is the baseline for future diffs.

Small-size readability

• Contrast: white mark on green fill — check both dim OLED and bright LCD.
• Silhouette budget: file, letter X, horizontal bars should remain readable after the store’s rounded-square crop.
• Lettering “X” must survive home-screen size; thin strokes usually fail first.
• illustration 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 表計算, not authoritative store scores.

Transferable design moves

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