USR369 confirmed via screenshot he does not use the Hide Done or Compact toggle buttons in the Exercises section header. Removed both <button> elements (id=hide-done-toggle, id=compact-toggle) from the header markup. Edit List button unaffected. toggleHideDone()/toggleCompact() JS functions left in place - both already null-guard on getElementById (if(!btn) return), confirmed safe to leave unreferenced rather than risk a wider edit for a cosmetic-only cleanup. node --check clean, deployed via file_write_web.php, read back live and confirmed both buttons absent from HTML.
