feat: render the portfolio through deep, tested modules

[DutchyD]

Summary

• Renders every page of the portfolio: sections (prose, hero, skills, q&a, contact, projects), the project index and detail pages, and the site footer.
• Four architecture passes shaped the seams: the Folio request path behind a resource table with injected fetch and locale-store adapters, a compiler-enforced Section registry, a closed Translate key set, a Navigation module that owns path comparison, and a Deliver seam that keeps server code out of the render path.
• A correctness sweep closed nine defects, including a honeypot that was announced to screen readers and silently dropped their messages, a blank .env.example copy that broke every page at boot, and provenance notices addressed by display position instead of wire position.
• 146 tests (from 26), split into node modules and jsdom rendering projects. Domain language is in CONTEXT.md; decisions in docs/adr/0001–0004.

Test plan

• pnpm test — 146 passing
• pnpm run typecheck — clean
• pnpm exec biome check — clean
• pnpm run build — client bundle verified free of server code and mail credentials
• Manual pass over /, a content page, /projects and a project detail against the live API
