Layer Names writes readable ids plus data-name with the original name
whenever the id differs; Minimal writes only the ids definitions need;
Unique prefixes every id and CSS class with a content hash, so SVGs
inlined in one page never collide. Import names objects and layers from
data-name, inkscape:label, serif:id or aria-label.
