The d2 drawing template compiles a diagram's source to SVG through the d2 binary (resolved via the D-104 path layer), then paints it with the same renderer the svg card uses. `clide draw --file x.d2` infers the type from the extension; `.svg` files render directly. Template handlers now return a DrawResult so a compile failure or an unresolved d2 surface as an honest userError with an install hint, not a generic "no SVG". Real d2 0.7.1 verified end to end.
