"""sw.py — website-refresh 2026-10-08 screenshot helper. A shim over the catalog's box client
(app-catalog-felhom.eu/scripts/box_walk.py, read-only), TARGET 9202, with ONE change: guest() pipes the script
into `pct exec 9202 -- bash -s` over `ssh hp`, so nothing is written on the demo-hp host itself (no pct push,
no temp file there). SC (0600 scratch with `.ctlpw`) and EV come from the environment. No secret is printed."""
