Matches findr-web's pattern: the image declares its own healthcheck against /healthz, so Compose doesn't need to restate it. Signed-off-by: Peter Siegmund <mars3142@noreply.mars3142.dev>

# Two things this file works around:
|
|
# - NODE_ENV=production makes `npm ci` skip devDependencies, and the build
|
|
# needs tsup + typescript from there. So NODE_ENV is set in the runtime
|
|
# stage only, not globally.
|
|
# - The npm 10.9 that ships with node:22 aborts `npm ci` with EBADPLATFORM on
|
|
# esbuild's cross-platform optional packages (pulled in transitively via
|
|
# tsup). npm 11 handles them correctly.
