/* ==========================================================================
   Kids, the Apple layer (2026-10-15). Loaded right after kids.css and refines it through the cascade only: same
   class names, same tokens, no markup or JS contract changes. Direction: "Swift Playgrounds for a 5-year-old".
   - Playful colour and characters stay (Khatu, the glazed khatam tiles, the five glazes); the craft is Apple's.
   - One geometry: radii 16 / 24 / 32 and capsules; no white rims, no hard 3D ledges. Depth is a soft, warm shadow
     (--kza-e1/e2) and, on coloured controls, a gentle inner shade (--kza-lift) so they still feel like toys.
   - Calm ground: warm paper without the lattice; chrome is a translucent material (blur + saturate).
   - Touch: feedback on pointer-down (scale), spring release (--spring); targets stay 56-72px for children.
   - Child pages stay always-light on purpose (kids.css); parent pages and the landing follow the grown-up site.
   - Reduced motion: no scaling, a brightness dip instead; reduced transparency: solid bars; more contrast: borders.
