/* ---------- SVG LOGO PALETTE ---------- */
/* The class contract for exported logo SVGs, so artwork carries classes
   instead of an embedded <style> block. Tag paths in Inkscape's XML
   editor, save, drop the file in — no post-processing.

   ONLY applies to INLINED <svg>. An <img src="…svg">, background-image,
   <object> or <iframe> is a separate document: neither these rules nor
   the custom properties they reference cross that boundary.

   !important because a raw Inkscape export writes style="fill:#333333"
   on every path, and an inline style attribute otherwise outranks a
   class rule. This also overrides the embedded <style> block in older
   exports, so existing artwork keeps working untouched. */
