   ChalkPix — Redesign v6 (dark theme, finalization pass)
   - Hover tooltips are now a single JS-positioned element measured against
     real layout (getBoundingClientRect), so they cannot overlap sibling
     rows regardless of how the rail wraps.
   - Featured Work: 3D rotating carousel (same mechanic as the old badge
     carousel). Why ChalkPix: simplified to a static grid (same visual
     language as Problems).
   - Solutions hub-grid tightened; every node now has a hover popup.
   - Process steps carry real descriptive copy.
