This path is read live from wherever the app is actually running right now — it's correct whether you're testing with python main.py or running the finished .exe on another computer.

Click the small tab to open/close the ribbon. Click a team's number to change it. 👍 triggers a celebration (configured in Thumbs-Up). ⚙ opens Settings. The colored strip is "shuffle" — randomizes turn order for active teams. The class-name button opens Settings on the Classes tab.

Click 📋 to switch into Attendance, "← Points" to switch back.

New class: use "Import roster (CSV)" — needs columns Student Number, English Name, Korean Name, and optionally Status (rows marked LEFT are skipped).

Daily marking: click a cell to cycle blank → O (Present) → / (Absent) → L (Late). Click the strike number to cycle 0–6. The small 📄/📝 icon next to strikes is for notes — click to add or edit one, hover the cell to read it. "All" cycles the whole class through Present → Absent → Late → clear. "Update" forces an immediate save.

Expand ⇤ shows full history — every date, two scrollable tables. Click any past cell to correct it; corrections are logged quietly, separate from today's normal entry.

saved_scores.md — current point totals, regenerated every save, always overwritten.
Weekly backup — a dated points snapshot once a week, keeps the last 8 weeks. Automatic, points only.
Full export (Settings → Classes → "Export Full History") — everything: every class's points plus complete attendance and strikes history, every date. Manual — click it, then move that file somewhere safe yourself. Nothing is ever auto-deleted from your attendance records.

Window doesn't appear at all: close every terminal/process for this app (Task Manager → End Task on anything named python or Classroom Ribbon), then try again from one fresh terminal.

A class or roster seems to have vanished: check the Data Folder above for data.json — if it's really gone, the weekly backup or your last full export is the way back.
