        Field names mirror the boardroom and ceo/settings frontends: the

        new limit is carried as ``new_limit_php`` (typed str on the wire

        because both frontends send ``JSON.stringify({ new_limit_php:

        newLimit, ... })`` where ``newLimit`` is a raw text-input string).

        The handler coerces the value to Decimal via ``Decimal(str(...))``

        -- it is NEVER typed float per rule #1. ``sandbox_token`` carries

        the body-field form of the CEO sandbox token used by the sandbox

        reference contract (see mock_fintech_app.py line 309).'
