  "message": "[vector-paint-pdf] Use scale_precision for transform matrix entries\n\nThe PDF push_transform and per-glyph cm were emitting\nmatrix entries (xx, yx, xy, yy) at default precision\u003d2.\nFor small values like 1/31.25 \u003d 0.032, this rounded to\n0.03 — a 6.25% error that accumulated through nested\ntransforms, visibly distorting color emoji rendering.\n\nUse scale_precision (min 7) for matrix entries, matching\nthe SVG paint backend.\n\nAssisted-by: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n",
