1.3. Re-design the topic page

This project focuses on redesigning the Oppia Topic Page to make it more intuitive and easier for learners to navigate. Currently, lessons are presented in a story-centric layout, while practice and revision content are separated into different tabs, which can cause learners to miss important activities and struggle to decide what to do next. The redesign introduces a unified interface where lessons, practice, and revision content are combined into a single continuous flow. Learners will see a structured, scrollable sequence of lesson and practice cards with clear progress indicators and actions such as start, resume, and review. It also improves how language options are displayed and selected directly on the Topic Page.
