These presets were hand-drawn approximations and looked visibly different from PowerPoint's (the lightning bolt had 7 points instead of 11, the explosions were different polygons, the cloud a ring of lobes without creases). They now follow ECMA-376's preset geometry, checked against the outlines PowerPoint gives for them (black-box: merging each preset with a far-away square and reading the resulting freeform): - lightningBolt, irregularSeal1/2: the standard's polygons (21600ths); - heart: its two cubic curves; - cloud (and cloudCallout's outline): the standard's eleven arcs drawn in the path's own 43200-unit square, plus the crease arcs, stretched to the box; arcs take DrawingML's angle convention (direction from the centre), new Pb::arc_spec; - flowChartDocument, flowChartMultidocument (three pages, outlined where they show), flowChartPunchedTape (half-ellipse edges). Wild synthetic set (per-shape mean diff, 1:1 gallery): lightningBolt 64.1 -> 2.8, irregularSeal1 41.1 -> 5.3, irregularSeal2 41.2 -> 4.8, cloud 28.2 -> 4.0, multidocument 30.9 -> 7.0, punched tape 27.7 -> 4.1, heart 20.9 -> 3.9, document 15.3 -> 3.8. Whole set 5.05 -> 4.84. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
