/* The Nook frame (round 4): one layout for every game, plus Nook's shelf, each game's sub-menu on the shelf (phase 9)
   and the Grown-ups hold. Layout reference: docs/little-patterns-round-4/mockups/frame.css. Load before the game's own
   object stylesheet, with nook.css (the rig) and shared.css (dialogs).

   Frame pages put class "lp-frame" on <html>. The frame height follows the visual viewport (frame.js sets --app-h
   from visualViewport, falling back to 100dvh), so when a device keyboard or large text leaves less room the task
   card scrolls inside the frame and the shelf button, Help, Delete and Enter stay reachable. Zoom stays on.

   Layouts: phone portrait (Nook above the task); phone landscape under 520 px tall (Nook in a left column, task in
   the centre, actions in a right column; Words folds the bubble into the card); tablet from 760 px wide (Nook
   larger beside the task). Motion follows review-opus-pass-1 section 4 as amended by BUILD-BRIEF items 60 and 64:
   travel at most 12 px, scale at most 1.06; Softer and reduced motion keep only short opacity changes. */
