Around the Corner bends every spell, hairpins included

Browse Source 
Two holes, found when a SAFE cast at a treasure 'around the 180 degree
corner' refused with no line of sight (room LZ5R). First: the bend was
honored only in the attack path — every neutral resolve (creations,
summons, utilities, edge targets) checked straight sight and ignored
the attached card, though the card says 'any line of sight spell'.
castSight/castSightEdge now thread the bend through all of them, and
the chronicle narrates the neutral bend too.

Second: the bend itself pivoted only at cell centers, so the card's
flagship shot — doubling back up to 180 degrees around a wall's end —
never resolved: both legs graze the corner and die. The pivot may now
sit in the wall's open gap itself (bentSightThroughGap), which is what
rounding a corner physically is. Closed doors still block; two corners
still refuse.

The client lights bent-reachable squares for real now instead of the
old one-step-adjacency guess, creations included. Pure widening, so no
rev bump: every one of these casts was refused before, so no ledger
holds one. All 26 production ledgers replay clean; the LZ5R moment
itself replayed and the exact refused cast now lands.
