/**
 * The two ambient facts an activity card needs from the screen around it:
 *
 *  - the deck's own notes text, so the feedback panel can show the passage an
 *    answer came from (NotesSource). Absent on screens with no notes (the
 *    homework guide's checkpoints);
 *  - whether reveals are off (exam mode), which hides the hints *and* that
 *    passage — both give the answer away.
 *
 * Its own module (not shared.tsx) because NotesSource needs these hooks while
 * shared.tsx renders NotesSource; a cycle there would be fragile.
