The workshop walks through warps; conjurations wear their own inks

A stride into a warp mouth now carries the walker out of the paired
mouth mid-glide, body turned exactly as the rays turn — canWalk admits
a rim edge only where a mouth waits, and the crawler splits the stride
at the crossing. And with painted conjuration sprites arriving, the fx
pass composites them normally instead of additively: painted art is
ink, not light, and additive blending would bloom its outlines white.
