# Build the v2 documentation site for this checkout into `site/`.

# Zensical runs no MkDocs plugins or hooks, so the build is three steps:
# materialise the API reference pages and the concrete config, build the
# site strictly, then generate llms.txt and the per-page markdown
# renditions. This script is the single owner of that recipe, dependency
# sync included — CI (shared.yml, docs-preview.yml) and scripts/build-docs.sh
# all call it. The toolchain detection in docs-preview.yml and build-docs.sh
# keys on this file's path and expects the site under site/.
#
# Usage:
#   scripts/docs/build.sh
