## Notes for LLM consumers

- Spanish (`es`) is the canonical default; English copies use the same content adapted, not auto-translated.
- Project bodies embed two `<section data-lang="es">` and `<section data-lang="en">` blocks; the inactive one is hidden via CSS, but both are present in the served HTML. When extracting, pick the section matching the URL prefix (`/` → `es`, `/en/` → `en`).
- Dates in project frontmatter are ISO 8601. `updated` on `/about` reflects the last manual edit.
- The site permits all major AI / LLM crawlers — see `robots.txt`.
