"""gallery.py — build screens/README.md: every screenshot, phone and computer side by side, HU and EN (Part E).

Files named `<prefix>-<phone|desktop>-<hu|en>.png` (tools/shot.py) are grouped by prefix into one row each; anything
else (console captures, bind.py's numbered shots) is listed under its folder. Relative links only, so the operator can
look without a box. Before writing, every image is listed with its size so a reviewer can spot one that was never
checked for a secret (rule 4: a screenshot that shows a secret is deleted, not committed).
usage: gallery.py <screens dir>
