InDesign writes fades as luminosity soft masks whose group is one extended axial `sh` over the whole page. hayro 0.7 sampled every such shading pixel by pixel through the shading function, so a report page with 40 of them took 10-15 s at 144 dpi. Backport hayro 0.8.0's `gradient` module: an axial or radial shading that a native gradient draws exactly becomes sRGB stops (within 0.01 per channel, a stop at every stitching bound), painted as a vello_cpu gradient. Upstream's half-pixel shift is left out: it suits vello_cpu 0.3 but moves 0.0.8's gradients off pixel centres. Page 4 of the reported file: 10.8 s -> 1.0 s.
