# ── 1. Install Python deps first (as root) so we can use playwright CLI ──
COPY requirements.txt /tmp/requirements.txt
RUN pip install --no-cache-dir -r /tmp/requirements.txt

# ── 2. Let Playwright install ALL required system libraries automatically ──
#    This is the official way — it knows exactly which libs are needed
#    and avoids the manual guesswork that caused missing libXfixes etc.
RUN playwright install-deps chromium

# ── 3. Create the mandatory HF user (UID 1000) ──
RUN useradd -m -u 1000 user

# ── 4. Install the Chromium browser binary as the non-root user ──
