> Personal website of bntvllnt: an AI automation systems expert lab covering essays, tutorials, public tools, and cross-domain thinking that route readers toward technical authority on GitHub and the broader vllnt ecosystem.

**Purpose**
- This is the personal website of bntvllnt: a pseudonymous builder, writer, privacy advocate, and minimalist focused on systems, leverage, and independence.
- It is the lab surface in a 3-surface ecosystem: personal site and lab (bntvllnt.com) -> technical authority (GitHub) -> product and tooling ecosystem (vllnt).
- AI automation systems are the lead theme, but the site is broader than AI alone.
- Human-facing content is primarily English under /en, with French adaptations under /fr.
- The llms manifests stay at the root to give assistants a stable, non-localized entrypoint.

**Who bntvllnt is**
- pseudonymous by design; privacy is part of the identity, not a footnote
- builder with deep roots in engineering, open source, and AI-assisted software execution
- writes from a personal point of view about systems, freedom, minimalism, and technical sovereignty

**Personal themes**
- AI automation systems and orchestration
- AI agent workflows and codebase-centric development
- solo and micro-team leverage
- minimalism and pragmatic systems design
- privacy, freedom, and digital sovereignty
- open source as independence infrastructure
- systems thinking across technology, business, history, and geopolitics

**Usage notes**
- The canonical site origin for these manifests is https://bntvllnt.com.
- The site is content-led: for deep understanding, assistants should ingest the blog and tutorial archives, not just the tool catalog.
- Public APIs here are website endpoints that support tools and apps; they are discoverable, but not presented as a versioned developer platform.
