Adds a new standalone /deepdive page with its own platform.css/platform.js, wires it into the dot-nav as an external entry, and updates the dot-nav docblock to reflect the new seven-entry layout. Also drops in BUSINESS.md and reference material under architecture boxes/ and examples/. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
