Gauss now writes a canonical metadata namespace declaration on saved SVG files:
xmlns:gauss="https://gauss.dev/ns/metadata/1"
This prepares metadata round-tripping work while keeping rendered artwork standard SVG.
- Gauss accepts SVG files that use this canonical
gaussnamespace. - If an SVG binds
gaussto a different Uniform Resource Identifier (URI), open fails with an explicit error. - If Gauss metadata namespace content is present without canonical
xmlns:gaussdeclaration, open fails with an explicit error.
