/* The studio (docs/STUDIO.md): a bright desk. Chats are paper notes, previews sit on a checkerboard mat, Locky holds the
   pencil while Claude works. Mode cards are plain buttons; your messages sit right, Claude's left. One column under
   720px, the box sticks to the bottom on phones, previews never wider than the screen. */
