/**
 * Layer TanStack `initialData` / `placeholderData` over a raw query result as a DISPLAY fallback.
 * Only while the result is still `Initial` (pending, never settled): show `initialData` as resolved
 * data, or `placeholderData` as provisional (`waiting: true`). Once real data exists the seed is
 * dropped. Failures are never masked — including failures without `previousSuccess` (where
 * `AsyncResult.value` is empty). `placeholderData` in function form receives the last seen concrete
 * value for basic keep-previous across input changes. Returns the raw ref untouched when neither
 * option is set. Neither value is written to the atom cache.
