# Multi-stage build: bun for installs (fast), node for build + runtime.

# The bun install steps use a BuildKit cache mount (/root/.bun/install/cache, both stages
|
|
# run as root) so the package cache persists across builds on daemons that keep named
|
|
# caches — notably the CI runner's shared dind daemon; where it doesn't persist it costs nothing.
