   WAJD Group front door, showcase edition v2 (18 Oct 2026)
   Light warm bone page; ONE contained warm-charcoal hero card holds the
   signature object (the exploded operation). Sora + Inter. Amber actions.
   Motion is scroll- and pointer-driven (front.js sets --p, --s, --tx, --ty,
   --mx, --my, --rx, --ry). Nothing runs while the page is idle.
   No inline styles: the site CSP is style-src 'self'.
