A SOLID's filled quad and a dimension/MultiLeader text background are flat 2-D overlays that should draw in wireframe and shaded alike, but face3d_gpu classified fills by `!fill_tris_low.is_empty()` — and a 2-D fill at UTM scale carries a double-single low residual for precision just like a real 3-D mesh face. So the arrowhead fill and the "5;8" cyan text background were routed to the 3-D buffer and only appeared in shaded mode, vanishing back to nothing on return to wireframe. WireModel now carries an explicit `fill_is_3d`: true only for a real surface (PolyfaceMesh / PolygonMesh face, set in the tessellator), false for every flat overlay fill. face3d_gpu classifies on the flag, so 2-D fills stay in the always-visible buffer while keeping their low residual (and UTM precision). Verified on budweiser: the `_BoxFilled` arrow SOLID and the dim '5;8' MTEXT background both tessellate with fill_is_3d = false. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
