simplify Tolerance Pixels
RDP+radial simplify tolerance, in tile texels (≈ screen px at the tile's level), applied to each tile's geometry before tessellation; 0.0 disables. WFS GetFeature returns full-resolution geometry at every zoom (unlike pre-simplified MVT), so the default ~1px drops the sub-pixel detail that would otherwise bloat tile memory and earcut cost without any visible change. Raise for smaller/faster tiles, lower toward 0 to keep every server vertex.
