   VINCAX — style.css
   Built in the shadows.

   Edit notes for future v2:
   - All colors live in :root as CSS variables. Change once,
     applied everywhere.
   - Type scale uses clamp() for fluid sizing — desktop and
     mobile values are encoded in each clamp.
   - Spacing tokens follow an 8px-base scale.
