# =============================================================================
# Platform nginx — Rocky Linux 9
# Construit ja4ebpf (eBPF CO-RE) + nginx avec HTTP/2 et TLS.
#
# Multi-stage :
#   ebpf-builder  — compile les programmes eBPF C avec clang
#   go-builder    — compile ja4ebpf (go generate + go build)
#   runtime       — nginx + binaire ja4ebpf sur Rocky Linux 9
