怎麼算的：每一週是星期一到星期日，標題用 YYMMDD~YYMMDD。數字只計 App Store 的首次下載，不含重新下載與更新。以 Apple ID 歸戶，所以 App 改名不會斷掉。

欄位順序：依上架先後由左到右，新 App 往右加——回頭看舊週次時欄位不會跳掉。表格太寬請左右捲動。

更新方式：appstore_sales_entry.py 每天寫入帳本，appstore_weekly_web_entry.py 每週彙整後推上來。標記 未完整 的是還沒收滿七天的當週。

How it's counted: each week runs Monday to Sunday, labelled YYMMDD~YYMMDD. Figures count App Store first-time downloads only — no redownloads, no updates. Apps are keyed by Apple ID, so a rename doesn't break the series.

Column order: by release date, left to right; new apps are appended on the right, so older weeks keep their columns in place. Scroll sideways when the table runs wide.

How it updates: appstore_sales_entry.py appends to the ledger daily; appstore_weekly_web_entry.py aggregates and pushes weekly. A week tagged partial hasn't finished its seven days yet.
