# dev.nu โ€” one-step rebuild + restart for local dev.
#
# Run this after ANY change under ~/cyberia-to/optica (Rust source,
# templates/*.html, static/*.css|js|woff2). Optica's binary embeds
# templates and static assets via include_str!, so editing the source
# files alone has no effect on the running serve.
#
# Sequence: cargo build (release) โ†’ kill any running optica serve โ†’
# launch a fresh serve in the background. Returns once the new serve
# has started; readiness is then verified by the caller.
