California Prop 65 (lead) + EPA + state fishing-line bans, how do you handle the compliance UX?

Three compliance fronts that catch fishing-tackle ecom off-guard:

• California Prop 65 lead warnings, lead jigs, lead split-shot, lead-core trolling line, and lead-weighted soft baits all need a Prop 65 warning at PDP for any California shipment. Magento pattern: a custom “prop65_warning” product attribute → block displays the regulation-compliant warning text + URL to oehha.ca.gov.
• EPA + state fishing-line bans, New Hampshire, Massachusetts, New York, and others ban monofilament sales without recycling-program signage. Maine + Vermont restrict lead split-shot under 1oz entirely (can’t ship; geo-block at checkout). Pattern: state-level shipping restrictions on flagged SKUs via Magento native shipping-method per-product rules.
• Federal lead-fishing-tackle restrictions on certain National Wildlife Refuges, mostly an in-store concern but worth a footer disclosure if you sell lead gear nationwide.

Compliance UX matters: clear Prop 65 warning at PDP (not buried), state-restriction message at checkout (not after payment), recycling-program link in the footer. None of this hurts conversion; bad surprises at checkout do.
