# Redeclare CACHEBUST — ARGs don't cross stage boundaries, so the builder
# stage's declaration never reached this stage. Consuming it in the RUN below
# busts that layer's cache every CI run (CACHEBUST=github.run_number), so the
# image always picks up current Alpine security updates instead of reusing a
# stale cached upgrade layer.

# Upgrade the npm CLI in the final image so its bundled deps are patched
# (sigstore 4.x, tar) — closes CVE-2026-48815 and the older @sigstore/core / tar
# Trivy alerts. Safe here: only the CLI present in the image changes. Runtime
# dependencies come from the builder stage (COPY --from=builder node_modules
# below) and the entrypoint runs node, not npm — so npm 11's install behaviour
# (the reason 10.x was pinned) never executes in this stage. npm 11 needs
# Node >=22.9, satisfied by node:22-alpine.

# Install dumb-init for proper signal handling, postgresql-client for database
# checks, ffmpeg for video upload support, and su-exec for the root → nodejs
# privilege drop in wait-for-db.sh (see #484: container starts as root so it
# can chown bind-mounted host volumes to UID 1001, then re-execs as nodejs
# before running the app). Alpine's ffmpeg package ships both `ffmpeg` and
# `ffprobe` built natively against musl libc — the npm
# `@ffmpeg-installer/ffmpeg` binary is glibc-built and (a) doesn't reliably
# run on Alpine and (b) only includes ffmpeg, not ffprobe (which the video
# pipeline calls via fluent-ffmpeg.ffprobe()).
# fontconfig is required so `sharp` (librsvg) can rasterise SVG logos that
# contain live <text> for the CRM PDFs. Without any font installed, librsvg
# renders text as tofu boxes (□) while the vector artwork still draws — i.e.
# a "corrupted" logo on invoices/quotes. DejaVu/Liberation provide a broad
# Unicode fallback; picpeak's own brand fonts (assets/fonts/, the same files
# PDFKit + the web UI use) are registered with fontconfig further down so the
# logo's text renders in its actual typeface, not a fallback.
# poppler-utils provides `pdftoppm`, used to rasterise inbound supplier-invoice
# PDFs to flat PNGs server-side so the admin UI NEVER renders a raw (possibly
# malicious) PDF. pdftoppm does not execute embedded JS or fetch remote
# resources, so it doubles as the SSRF/phone-home guard for untrusted inbound
# documents (see docs/accounting-inbound-invoices.md).
