"""
halve-banner.py — halve the collection-hero banner min-height on each run. Reads the
current `min-height:clamp(Apx,Bvw,Cpx)` in the live theme's dw-collection-hero.liquid
and rewrites it to half of A/B/C. Idempotent-safe (just halves whatever is there);
run again to halve further. Backs up first.
Run:  ! python3 ~/Projects/secrets-manager/halve-banner.py            # dry-run (shows old->new)
      ! python3 ~/Projects/secrets-manager/halve-banner.py --apply
