The course stays central — the exercises become yours. Lessons, videos and slides live on the course's own pages and keep updating. The hands-on material — exercises and demos — is installed into your own space, where every page is yours to edit, run and break.

The one idea

Every module ends in three graded workbenches:

• 🟢 Easy — a warm-up you can finish in minutes.
• 🟡 Medium — the real thing.
• 🔴 Hard — the stretch goal.

Each exercise ships deliberately red: the checks are written, the implementation is a stub. You (or an agent you direct) drive it green — the live cell on the page re-runs as you edit. A solution is one click away on every exercise, and your copy never touches the course's original.

Working in your own copies

Press Install on the course page: a dialog lets you choose what to install (exercises, demos) and where — a namespace in your own space. From then on:

• Go to Exercises takes you straight to your copies.
• Update from course re-syncs anything you haven't touched when the course evolves; your edited pages are left alone.
• Not installed yet? Any exercise link into your space will tell you so and offer the install dialog — nothing is copied behind your back.
