/**
 * The theme editor's working copy.
 *
 * The panel edits this copy and pushes every change out through the
 * `onupdate*` callbacks, exactly like React's `ThemeEditorPanel`: the host owns
 * the committed theme, so the panel never mutates the `theme` prop.
 *
 * `initialTheme` is captured with `untrack` at construction, which is
 * load-bearing twice over: it seeds the working copy without the read counting
 * as a reactive dependency (Svelte warns otherwise), and it pins the value
 * {@link reset} reverts to, so Reset still restores the file's theme after a
 * dozen edits have flowed back in through the `theme` prop.
