    Wire spellings of every query parameter the viewer recognizes.

    This is the URL contract in one place: readUrlParams consults it for every key, the README-parity unit test checks each value is documented, and embedders that assemble a viewer URL read the spelling from here instead of hardcoding it. Multi-word parameters are camelCase (noCache, lodFinest); single-word parameters are unchanged. The table key and the wire value are identical on purpose — URL_PARAM_KEYS.noCache reads as the flag it names, and the identity keeps the type UrlParamKey equal to the set of wire spellings.
