Hit the scaling cliff at $5k? Backing off 50% reset it

Scaling cliff (the point where adding budget tanks performance instead of growing it) — pushed $4k to $5k and CPA went $38 to $59 and STAYED there even after I lowered budget back.

The reset that worked:
— Cut budget HARD, $5k down to $2.5k, not a gentle trim
— Held the cut for 3 full days to let the auction re-stabilize
— Re-ramped at 15%/48h from there

CPA fell back to $40 within the cut, then I climbed to $4.2k clean.

Risk: a hard cut can drop you out of learning and cost you a few unstable days. But limping along above the cliff bleeds more. Cut deep ONCE rather than nibbling budget down.
