SVG active content validation

[gentiprenaj]

Shopware tightened what it allows inside SVG icons, so I need our payment logos exported a specific way from now on. Nothing wrong with the art itself; the platform just rejects certain things inside the file.

New svg rules for Shopware6 :

• No embedded images. Don't place or paste a PNG/JPEG into the artboard and export — that "embeds a picture inside the SVG," which gets rejected. The icon needs to be real vector shapes, not a photo wrapped in an SVG. (This is what tripped up Alipay, Carte Bancaire, TWINT and SNS.)
• No filter effects. Drop shadows, blurs, and the opacity-mask/"color-matrix" filters that Illustrator/Figma auto-add on export get rejected. Please expand/flatten effects into plain shapes before exporting. (This tripped up nn and Carte Bleue.)
• Gradients are totally fine — as long as they're actual vector gradients, not a gradient flattened into an embedded image.
• Export "clean/minified" SVG (or run it through SVGO). That strips leftover editor junk like baseProfile / enable-background, which Shopware also disallows.

Rule of thumb: if you open the exported .svg in a text editor, it should contain only vector stuff (path, rect, circle, linearGradient, etc.) — no < image>, no < filter>, no <script>.
