Important product boundaries:
- Browser-local HSK1 progress, returned-paper marks, copied handoffs, account access, uploaded files, reminders, and billing state are separate unless a user explicitly exports or follows a same-set link.
- Payment uses hosted checkout after sign-in; checkout recovery should check billing, account overview, and learner profile before retrying pricing.
- Lang Study is specific to the current Chinese character workflow while leaving room for future writing systems.
