# Resolve the application version from .git at build time and emit a tiny
# .build-version file. The .git tree is consumed in this throwaway stage and
# never copied into the runtime image; only the tag + commit version string
# ships. Non-main builds include the branch name so they are visibly distinct
# from release builds. This matches the runtime fallback chain in _resolve_app_version
# (REMNAWAVE_MINISHOP_VERSION env > .build-version file > live git >
# "dev+unknown") so the admin sidebar always shows a tag / sha even though the
# runtime images have no git tooling and no .git tree.

# The Mini App shell is rendered by the backend, which rewrites the stylesheet
# and script tags to the content-hashed asset names (subscription_webapp.<hash>.css).
# Those hashed files are build artifacts and gitignored, so a clean checkout has
# none of them: without this copy the asset resolver falls back to the bare
# /subscription_webapp.css URL. That URL never changes between deploys and is
# served no-store, which iOS WebViews (WKWebView) cache aggressively and refuse to
# revalidate -> stale CSS and a broken-looking Mini App on iOS only. Pull the
# freshly built assets (the same hashes the nginx image serves) into the image so
# the shell emits immutable, cache-busting URLs.
