/* ---- Structure & targeting ------------------------------------------------

   Each EXERCISE (its `.ex` header + the items under it) is wrapped in
   `.exercise` with an id like `part4-ex3` and data-ex. So you can target:
     #part4-page2                     -> one page
     [data-part="4"]                  -> everything in Part 4
     #part5-ex3                       -> one exercise
     #part4-page2 .exercise + .exercise { margin-top: 8mm }  -> gap between
                                        exercises on that page

    instruction; `.exercise` is the whole block that header belongs to.)
