     - White / near-white fills (#fff, #ffffff, white) are kept as-is — they
       act as contrast cutouts in 2-colour logos (e.g. white letter on coloured
       circle).  Every other colour becomes currentColor.
-    - inline style="fill:#..." is rewritten to a fill= attribute.
+    - inline fill/stroke colours are normalized without discarding other styles.
     - Inkscape layer translate() transforms are stripped (canvas offset artefact).
