# One-shot installer for MicroslopSam. Runs all setup steps, idempotently:
#   1. record resolved paths in setup/microslopsam.env
#   2. system dependencies (Wine, Winelib, helpers; needs sudo)
#   3. wine prefix + SAPI4 runtime + MSTTS voices + registration
#   4. Flextalk extraction + voices + registration
#   5. host build (Winelib and PE)
#   6. quick voice check
#
# Paths and tools come from setup/config.sh. Override anything with environment
# variables (they win over setup/microslopsam.env), for example:
#   MICROSLOP_ASSETS=/srv/assets MICROSLOP_PREFIX=~/.wine-sam setup/install.sh
# Set MICROSLOP_UPDATE_ENV=1 to rewrite an existing microslopsam.env.
