D001: The site is the proof

Context: A conventional portfolio tells you someone is good. Saif's goal is subtler, the site should make you feel it.

Decision: Adopt one governing principle: every choice must be defensible as a deliberate product decision that demonstrates product-engineering + PM skill. Decoration for its own sake is rejected. Formalized as North Star - Site as Proof.

Why: It gives every later call a single test, "does this prove capability, or just look nice?", which is itself the prioritization skill we're selling.

Consequences: drives D002 - Tech Stack, D003 - Visual Restraint and One WebGL Moment, D004 - Case Study Framework, and the three meta-proofs Custom Analytics / Knowledge Graph / WebGL Hero.
