Your chapter, decluttered: projects, interview prep, and a story while you wait

One practice surface each, two new reasons to open a chapter, and a wait worth watching.

• Decluttered chapters: the duplicate inline flashcards and the "Walk me through it" button are gone - your check-for-understanding gate is the one flashcards queue, and Walkthrough lives where it belongs, in the study tabs. The standalone Quiz tab is retired too: quizzing already lives inside walkthrough checks and the chapter gate.
• The Exercise tab is now Recommended projects: two to three genuinely buildable projects per skill - starter to stretch - each with a build plan, self-verifiable success criteria, and a note on presenting it as portfolio evidence.
• New Interview prep tab: the questions interviewers actually ask about each skill at your difficulty band, with the shape of a strong answer, delivery tips, and the follow-ups they probe next. Answers stay hidden until you have attempted out loud - that is the practice.
• Every chapter now carries at least one short video (never longer than ~45 minutes) whenever a vetted one exists, found by a dedicated video search pass.
• Building a path is now a story, not a spinner: the generation journey unfolds stage by stage - mapping your skills, subtracting what you know, ordering the gap - with a fresh message every few seconds, and your new path's steps reveal one after another when it arrives.
