scripts/build_parity_gallery.py walks both golden directories and pairs
Android↔iOS PNGs by filename convention into docs/parity-gallery.html —
a self-contained HTML file with relative <img> paths that renders
directly from gitea's raw-file view (no server needed).
Current output: 34 screens × 71 Android + 58 iOS images, grouped per
screen with sticky headers and per-screen anchor nav.
docs/parity-gallery.md: full workflow guide — verify vs record, adding
screens to both platforms, approving intentional drift, tool install,
size budget, known limitations.
