feat: redesign product marketing surface

[0thernet]

Summary

Reframes Atet around the finished-media outcome, a concrete inspect/plan/run workflow, and the exact local interfaces that produce it.

• adopts Design Kit v0.3.0’s shared product-marketing contract while retaining Atet’s serif, gold, and night identity
• gives the first viewport a real four-command proof, product facts, clear boundary, and direct actions
• separates install, Agent Skill, CLI, SDK, and MCP examples into legible proof surfaces
• adds explicit trust boundaries, native FAQ disclosures, matching FAQ schema, and agent-readable Markdown
• keeps both the root and independently installable web lockfiles pinned to the immutable dependency

Focused verification

• bun test ./site.test.ts (35 pass)
• bun run build (25 static files)
• isolated bun install --frozen-lockfile --ignore-scripts for apps/web
• git diff --check

The local browser layout verifier could not bind a sandbox port; Required CI owns that browser gate and the aggregate repository check.
