/* ============================================================
   playful.css — "Sunny Classroom" skin (loaded LAST)
   ------------------------------------------------------------
   Kid-friendly re-skin of Home, Quiz (config + play) and Result
   for elementary-school learners and the parents beside them:
   rounder, chunkier, bigger type, a rounded display face (Jua)
   and tactile "toy button" presses.

   Override layer only — layouts still live in screens.css; this
   file restyles them via tokens (variables.css) so the white,
   black and blue themes all follow. Other screens only inherit
   the global bits in §1 (focus ring, buttons, chips, header/nav).

   Chunky press pattern: a solid bottom edge drawn with
   `box-shadow: 0 var(--press-depth) 0 <edge>` that collapses on
   :active while the element drops by the same amount — so it
   feels pushed in, and nothing below it shifts.

   Every animation added here is switched off in §6 for
   prefers-reduced-motion (base.css also clamps durations).
