FROM rust:1.96-alpine3.24 AS base
# sqlx's postgres driver speaks the wire protocol in pure Rust (no pq-sys in
# Cargo.lock) and TLS goes through rustls, so libpq headers are never needed at
# build time. perl/make/gcc/musl-dev remain for the C builds of aws-lc-sys.

# ─── Stage 1b: Build the SvelteKit frontend (Vite) ───────────────────────────
# Produces the SPA in /static-dist. `npm ci` is cached unless the lockfile
# changes; the Rust build no longer bundles assets (see build.rs).
