Frame — the live token
light  0 10px 28px rgba(15,35,70,.10)
dark   0 14px 36px rgba(0,0,0,.55)
Everything inside it — no shadow
Depth comes from the border on light and the surface step on dark.
🚨 This reverses DDS's "no drop shadows anywhere" — and it is FRAME LEVEL ONLY. Not on cards inside a list. Fourteen shadowed cards stacked down a screen is exactly the generic look this redesign exists to escape, so the shadow sits on the frame and on nothing inside it. The two values are the same shadow read for two grounds: a blue-tinted 10% on light, and a much deeper 55% black on dark where a tinted shadow would simply disappear. §4.
