/* Tutor library.
 *
 * Deliberately self-contained. Two earlier attempts leaned on the shared
 * stylesheet's tool classes and both came out wrong, because several rules
 * later in that 274 KB file resize `main` and flatten `.toolGrid`, and I
 * cannot see this page render to find out which of them win.
 *
 * So everything structural here is scoped to this page and stated outright.
 * Colours and the site chrome still come from styles.css; only the layout is
 * taken back, and only inside body[data-page="tutor"].
 *
 * The specific failure worth remembering: a grid whose text column was
 * `minmax(0, 1fr)` next to `auto` button columns. When the container got
 * narrow the buttons kept their width and the filename column collapsed to a
 * few pixels, so filenames rendered one letter per line. Nothing here uses a
 * fixed track for content that can grow.
