/* ==========================================================================
   Neft Teacher — Projects DECLUTTER layer (shared)
   Makes each step's Level-2 challenge opt-in: it collapses behind a
   "⭐ Optional Challenge" button (shown only at Level 2, since the block is
   already level-gated). No DOM is moved and no ids change — the block and its
   inputs stay in place — so Save/Resume, grading, and the report are untouched.
   Runs under body.declutter-projects. Injected by tools/inject-projects-declutter.mjs.
