# Self-contained SvelteKit Node bundle — `npm run build` with the
# docker-node adapter emits build/index.js plus a fully self-contained
# build/ tree. No node_modules needed at runtime, so RDEPEND only
# pulls nodejs for the interpreter.

# npm fetches several hundred packages (SvelteKit + Vite + Tailwind +
# Playwright + svelte-check + ...) from the npm registry at build time.
# Vendoring node_modules into extra-stuff would balloon to ~500MB+ and
# bit-rots on every upstream bump; lifting the sandbox is the same
# pragmatic call sci-misc/llama-cpp + sci-misc/llama-swap[ui] already
# make for their webuis.
