`URLSearchParams` is absent from the App-Plus JS core, and
`toLocaleDateString('sv-SE', { timeZone: 'Asia/Shanghai' })` depends on full
ICU data that the App runtime does not ship, so the work-result pages built
either a broken query string or the device-local date.
Build query strings with `encodeURIComponent`, and centralise the business day
in `currentShanghaiDate()`, which shifts the epoch by a fixed UTC+8 offset
before slicing the ISO date. Asia/Shanghai has no DST, so the fixed offset is
exact rather than an approximation.
