Reordered quick-start IA: sign-up → main path → first speaking first; featured reading follows a first-week path; retitled “From tryout to habit” so it doesn’t collide with “Three ways”.
Clarified product shape: full features in browser DodoTalk (Add to Home Screen); LINE is a light entry.
Plan articles match bottom tabs: personal Plan; Family / Teaching Space.
Family assign-tasks and speaking feedback scale rewritten as how-to only; usage pages add an at-a-glance points/benefits vs minutes-pool table.
Unified user-facing naming: Teaching (aligned with 教学 / 教學 / ティーチング); help body no longer uses “Teacher Pro” as the product name.
Removed internal doc references from user-facing copy; amounts and campaigns say “as shown in the App / campaign pages”.
Removed guest-mode negation phrasing; sign-in requirements use affirmative wording.
