Note, element and theme preference facades

addNote(options?): FacadeNote

Creates a jolly-property-row: field-aligned text with no bound value.

interface NoteOptions extends FieldLayoutOptions {
  label?: string;
  description?: string;
  descriptionDisplay?: "block" | "tooltip";
  align?: "start" | "end";
}

const note = folder.addNote({
  description: "Peer indicators outside the camera frustum are skipped."
});

note.description = "Updated copy.";

• label and description stay writable on the builder.
• Unset options keep the element defaults, after the pane's field layout.
• For richer markup, use note.element or addElement().

addThemePreferences(options?): FacadeThemePreferences

Creates a jolly-theme-preferences.

interface ThemePreferencesOptions {
  layout?: "inline" | "stack"; // default "stack" here
  storageKey?: string;
  target?: HTMLElement; // default: the nearest jolly-scope
}

chrome.addThemePreferences({ storageKey: "three-examples" });

layout defaults to "stack", unlike the element, so the controls line up with the pane's label column.

addElement(element): FacadeElement<TElement>

Appends an element the caller built and tracks it like a builder, so disposeAll() reaches it.

const preview = folder.addElement(document.createElement("canvas"));

preview.hidden = !settings.showPreview;

• preview.element keeps its type, here HTMLCanvasElement.
• Prefer it to element.append(): on a floating Pane, element is the window, so an appended child lands beside the pane.
