# --- Stage 1: compile Tailwind CSS + vendor JS deps ----------------------
# Runs the Tailwind JIT over views/, src/, and our JS so only classes that
# are actually referenced end up in the output. No runtime <style> injection,
# which lets the CSP drop 'unsafe-inline' for style-src.
#
# The same stage also vendors Alpine.js (CSP build), htmx, and SortableJS
# from npm into /build/vendor/ — copied into the runtime image alongside the
# CSS so the strict CSP can keep `script-src 'self'`.
