+// ROTATED image cards (the 5° spread significator + the 90°/270° cross) drop the
+// 4-cardinal CONTOUR-stroke chain, keeping ONLY the depth drop-shadow. Each
+// contour drop-shadow re-rasterizes the already-downscaled card image (408→64px
+// here), so a rotation compounds that re-sampling into visible BLUR — verified
+// 2026-05-30: a lone depth shadow on a rotated card stays crisp, the 4-shadow
+// chain does not (it's NOT the angle; even the 5° sig blurs). Upright cards keep
+// the full contour. The override sets `filter` outright (zeroing `--img-stroke-w`
+// wouldn't help — the blur is the chained-shadow re-rasterization, not the
+// offset). Source-ordered after the base + english rules to win the 0-3-0 tie.
