# Etiya doc-to-lora UI — local container deployment
#
# Usage:
#   1. cp .env.example .env.local        (or set HF_TOKEN in your shell)
#   2. docker compose up --build         (builds image, starts container)
#   3. open http://localhost:3000
#
# To rebuild after code changes:
#   docker compose up --build --force-recreate
#
# To inspect inside the container:
#   docker compose exec d2l-ui sh
