✦ Executive Design Audit & Architectural Deliverable

I have dismantled the generic card structure and rebuilt it according to

Apple Human Interface Guidelines (HIG),

Lamé super-ellipse geometry, and strict

anti-slop copy heuristics.

1. Verification & Copy Audit (tools/deslop.py)

Before generating code, the marketing microcopy was audited against the Slop Heuristics Database:
