Profile tiers

Switch profiles in Studio to retune default thresholds across the whole bundle without rewriting any control by hand. This package ships at strict — anything you've already tightened by hand is preserved on switch.

Every control in this package uses identical parameters across all four profiles. Switching profile in Studio has no effect here.

Attestation

The canonical hash of these bundle bytes is sha256:29a55dc69f1a70f225149ca6a37e2eb5c356eee01aff780eccdc3eb2338281d0. The same hash is computed at lock time, at Stripe checkout, and again on the runtime side before any byte is honored.

Want to customize first? Opening this package in Studio prefills the canvas with the 9 controls above. You can add, remove, or retune any of them before you lock the hash and pay.
