# syntaxis Installation Configuration
#
# This file defines installation presets, database backends, and service configurations.
# It serves as the source of truth for the enhanced installer system.

# Usage:
#   nu scripts/install-syntaxis.nu --preset local
#   nu scripts/install-syntaxis.nu --preset dev
#   nu scripts/install-syntaxis.nu --config my-install.toml
