Replace the platform fee table with a calculator the visitor drives The /pricing page held nine other platforms' fee parameters in assumptions.toml and rendered them as a sorted table. Three problems, all structural rather than editorial: it named competitors, every rate in it was an unmaintained claim about somebody else's pricing page, and a comparison whose contents we choose is a comparison we can rig. The other platform's fees are now two dials the visitor sets, so there is nothing to keep fresh and nothing to name. Inputs are item price, monthly sales, tier, and the other platform's percentage cut and per-sale fee, the latter two being its total deduction as read off a payout. Dropping "monthly revenue" for price times volume also removes a fudge: the old code estimated transaction count as revenue / an assumed average sale, so every per-transaction figure in the table was approximate. Sale count is an input now and the arithmetic is exact. The difference between the two sides is linear in sales, so the crossover is solved rather than searched for, and the branch where no volume ever closes the gap is a first-class result the page states plainly. Tests pin the flip one sale either side and the no-crossover case. Defaults open on a mid-market scenario, a $25 item at 40 sales a month against a common percentage-plus-flat-fee model, so the first render is realistic without touching a dial. Also removes the named comparisons from compare.md (rewritten around our own model and the crossover arithmetic), migration.md (reorganised by export class rather than by platform), pricing.md, merchant-of-record.md and tiers.md, plus two the audit had not listed: a competitor domain in the example profile layout and a competitor recommended as a tax service. Carries the lib.rs edit that 6fe9ee0f was waiting on, so the two restored files go back out with the module that replaces them.
