/* Clippy2027 app shell styles, shared by every phase. Phase styles live in
   their own files (office.css for phase 1).

   A Windows 98 skin on top of 98.css (vendor/98css).
   One maximized application window with a menu bar and fixed sections.
   No floating windows, no pop-ups: questions and prompts appear in a fixed dock
   in the Clippy section, and endings replace the app's contents.
   Mobile first: on a phone the app fills the screen. On desktop it sits on a
   teal desktop. 98.css is sized for an 11px pixel font on a 1998 monitor, so
   text and tap targets are scaled up here to stay usable on a phone. */
