# pip >= 25.1 is required for `pip install --group` (PEP 735 dependency groups).
# Install deps before copying app code so the deps layer caches across code edits.

# Bake the template and, if present, the local runtime config.yml (gitignored,
# like the old config/ dir) so the build picks up local customizations.

# ========= Scraper Image =========

# Playwright's bundled Chromium, NOT google-chrome-stable: Chrome has no
# Linux arm64 build, which forced amd64 emulation (Rosetta 2) on Apple
# Silicon — and Google's bot detection CAPTCHAs emulated browsers on /search
# (verified 2026-06-11: identical setup passes natively, fails under
# emulation). Bundled Chromium runs native on both arches.
