# ── Aanvalsoppervlak beperken ─────────────────────────────────────────────────
# Twee stappen die samen elke CVE uit de imagescan wegnemen. Ze staan hier en
# niet in een andere stage: alleen dit image gaat naar de registry.
#
# 1. OS-pakketten bijwerken. Het node-image wordt minder vaak herbouwd dan
#    Alpine patches uitbrengt, dus libssl3 en libcrypto3 lopen er structureel
#    op achter — goed voor twintig CVE's in de laatste scan. Dit haalt ze op
#    het moment van bouwen alsnog bij.
#
# 2. De pakketbeheerders eruit. De container start met `node src/server.js` en
#    gebruikt npm, npx, corepack of yarn nooit; ze zitten er alleen in omdat
#    het base-image ze meelevert. Alle negentien Node-CVE's uit de scan zaten
#    in npm's eigen meegeleverde dependencies (tar, pacote, sigstore,
#    brace-expansion, picomatch, ip-address) en hadden niets met deze
#    applicatie te maken. Weg met de tool is weg met die hele categorie —
#    inclusief de volgende ronde, want ze komen steeds terug.
