Pure picker — emits `array[floor(index)]` as a float. Index is clamped to [0, length-1]. The `array` input port wins when wired (non-empty); otherwise falls back to the `values` param. Fallback float returned when the resolved array is empty. Pair with textDecompose.itemSources (or any float-array source) to drive per-index side effects.
