/* ===== "Track a novel" dialog =====

   Opened by the mobile FAB and by the command palette's Track action, so it is
   not a mobile-only control despite the `fab-` prefix its markup carries.

   It could not be opened at all. `responsive.css` sets `.fab-modal {
   display: none }` at every width, five places add or remove `fab-modal-open`
   (command-palette.js, _shell/scripts.html, dashboard.html, library.html), and
   no rule ever defined that class. Tapping + did nothing; so did choosing
   Track in the palette. Tracking a novel is the product's primary action.

   The look comes from the `.mobile-more-*` bottom sheet that used to live in
   mobile-nav.css. Redesign §2.5 replaced that popover with this dialog, the
   template was rewritten to `fab-modal-*`, and the stylesheet was not — so the
   design existed the whole time under names nothing rendered. Those rules are
   deleted there and adapted here rather than written afresh.

   `.fab-modal.fab-modal-open` rather than `.fab-modal-open` alone: two classes
   beat the single-class `display: none` in responsive.css on specificity, so
   this does not depend on stylesheet order. */
