Split the Dockerfile into a builder stage (apk + pip cache mounts) and a
slim runtime stage, mirroring reimpasto. apk and pip package caches now
persist across builds and never land in the image layers.

FROM alpine:3.24 # syntax=docker/dockerfile:1
# Multi-stage production build for the kaya-rbcs app on the Kaya framework.
# Base: alpine:3.24 (python3 = 3.14). Deps are installed into a venv in the
# builder; apk and pip caches use BuildKit cache mounts so they persist across
# builds and never land in the image layers. Requires BuildKit (default for
# `docker build` / `docker buildx` on modern daemons).
