// The site's authored content, as code.

//
|

// This replaced content/{products,projects,legal,demos}.json and their
|
||
// runtime loaders. The reasoning: this codebase's whole style is making
|
||
// invalid states fail at COMPILE time (SafeHtml, integer money), while the
|
||
// JSON loaders did the opposite — a typo'd field silently dropped a variant,
|
||
// and one stray trailing comma once blanked every legal page at runtime while
|
||
// the server kept answering 200. Content edits go through git push and a full
|
||
// CI build regardless (there is no content-only deploy), so the "edit without
|
||
// a toolchain" argument bought nothing here. Now a broken product is a
|
||
// compile error, the wasm bundle ships four fewer files, and the duplicated
|
||
// keep-in-step loaders in main.cpp and the server module are gone.
|
||
//
|
||
// posts.json and rates.json remain data on purpose: shell pipelines write

|
||
// since both rails became self-hosted (2026-08-20) the leaks are a bank
|
||
// transfer's zero and, on the crypto rail, gas plus whatever an exchange takes
|
||
// at cash-out. Supplier prices are what the retailer currently charges (incl

// VAT); change one number when the supplier moves and the margin stays put.

The order is an offer to buy; the contract forms when the payment arrives. Until then nothing is owed: an unpaid order simply lapses and can be ignored. An unpaid bank-transfer order is held for about two weeks and a cryptocurrency order's address stays reserved for about a day; after that each lapses like any other unpaid order. In both cases a payment that arrives late is not lost, because the account and the address remain Catcrafts', and it is settled by hand on request.",

"Prices are in euros, and euros are what is charged; any amount shown in another currency is indicative only, converted at the ECB reference rate of the date shown. Inside the EU the shown price includes 21% Dutch VAT. Outside the EU the sale is a zero-rated export at the derived ex-VAT price, and the price then excludes import duty, import VAT, tariffs and any carrier handling or brokerage fee. Those charges arise on arrival in your country, are levied by the carrier or your customs authority, and are solely a matter between you and them: Catcrafts does not collect them, cannot bindingly estimate them, is not a party to their assessment, and refusal to pay them does not undo the sale. Your bank or card sets the actual euro conversion rate for whatever you pay with.",

A bank payment is an ordinary transfer you make yourself, from your own bank to the account shown on the order page, quoting the reference shown with it: that reference is what matches your payment to your order, and a transfer without it cannot be matched. Cryptocurrency payments are made in EURC, a euro-denominated stablecoin, directly to a wallet address held by Catcrafts and shown on the order page. Catcrafts never sees your card details, your bank credentials or your wallet keys, because at no point are you asked for them. Cards are not accepted.",
