Render screen-anchored “misclick” tap particles. These ignore the biscuit
rect — they live at the exact column/row the click missed at, so dead-zone
clicks visibly register even if no game state changed.
Render auto/click/golden/confetti particles. Positions are resolved
against the CURRENT biscuit rect from each particle’s fractional
anchor, so they travel with the biscuit on zoom/resize. area is the
visual clip (same as the resolution target).
