   OZYN.AI — Spacing, radius, shadow & motion tokens
   Spacing is a soft 4px-ish rhythm expressed in rem. Radii are
   generous: pills (999px) for actions/chips, soft rounding for
   cards. Shadows are whisper-quiet — long, very low-opacity drops;
   the system leans on hairline borders instead of elevation.
