/**
 * Shared option lists for surface settings UIs.
 *
 * These are the dropdown / radio / chip options every surface needs
 * to render the same choices the same way: the six OpenAI TTS voices,
 * and the three theme preferences.
 *
 * Previously each surface redeclared these inline. Now there's one
 * source — a new TTS voice added here shows up in every settings tab.
 *
 * The shapes are intentionally presentation-neutral: a key + label
 * pair. Each surface layers its own visual styling (chip vs radio vs
 * dropdown) on top. The key is what gets persisted; the label is what
 * the user sees.
