Rewrite a sales page for the skeptic

Rewrite this sales copy for a skeptical, experienced buyer who has been burned before: {{paste copy}}. Product: {{what it is}}. Audience: {{who}}.

Apply these moves:
1. Replace every claim with a specific, checkable version — numbers, mechanisms, named constraints.
2. State the limitation up front. Say who this is not for, plainly.
3. Show the mechanism: why it works, in one paragraph a practitioner would nod at.
4. Put proof adjacent to each claim, not in a testimonial section.
5. Answer the four skeptic questions inline: how long until it works, what happens when it doesn't, what it costs in my time, and what I'm locked into.
6. Cut every superlative and every sentence that would survive being about a different product.

Output the rewrite, then a table of Original claim | Why a skeptic disbelieves it | Replacement. Mark any claim I need to verify or soften for legal reasons.
