/* Shared flashcard study screen — one flat card in the focused `reviews` layout.
   Used by /reviews, Kindle, and the root / present verb / past verb reviews.
   Adapted from the Kindle (Cardsmith) card, built on AbjadPro's --color-*
   tokens so light and dark mode both follow the site theme.

   Class names are `study-*` on purpose: the global `.btn` / Pico button rules
   use !important fills and the Playfair face, and new names sidestep them. */
