⚠ The per-province central meridian table (data/vn2000_provinces.txt) is for reference only — verify against official documents before using for legal records.
Vertices convert exactly. Circles, arcs, ellipses, text and blocks have no exact image in a
different projection — they are converted with a local similarity (scale + rotation measured
at each object), leaving a small residual error that grows with object size. Undo restores
everything in one step.
