    "inscription": "A carved line is at most 280 bytes, permanent and public. It cannot be edited or deleted by anyone, including the station.",
    "toll": "The exact toll is read live from the Monument contract (price()) at carve time — this file never hard-codes amounts.",
    "witness": "One witness patch per address, soulbound: the badge contract rejects every transfer. Qualification is a prior inscription on the Monument, proven on-chain.",
    "protocolFee": "The protocol takes nothing from carves. The toll moves from the carver to the dead address in the same transaction — verifiable in the Transfer event of any carve receipt.",
    "funding": "The site and contracts never hold user funds. Approvals are for the exact toll of one carve, never unlimited."

    "This file describes mechanisms, not performance. Nothing here is financial advice and no return is promised anywhere.",
    "The wall reads live chain data through a public RPC; when the RPC is unreachable the wall says so and keeps the last checked state.",
    "Inscriptions are permanent and public. Anyone can read them; the wall does not moderate chain contents.",
    "Wallet flows are self-hosted signing: keys never leave the visitor's wallet, and every transaction is individually approved."
