Approximate height based on font size and number of lines.

Approximate width based on character count and font size. This is a rough estimate; actual width depends on the font.

Get as a kurbo Ellipse.

Reconstruct nested groups from Excalidraw group paths. Each entry is a shape plus its `groupIds` ordered innermost -> outermost. Elements sharing the

Auto-save document to IndexedDB (silent, no logging).

Get the background color (for clearing).

Bring a shape to the front (top of z-order).

Broadcast message to room

Emit a subgraph cluster box and its title label.

Emit the connector (arrow or line) and optional label for one edge.

Emit an edge label with an opaque background so it stays legible over lines.

Load the publish-date cache, tolerating a missing or corrupt file.

Persist the publish-date cache, creating parent directories as needed.

Draw a remote user's cursor at a screen position. The cursor is rendered as a small pointer arrow with the user's color.

Read an element's `groupIds` as owned strings (empty when ungrouped).

Emit all shapes in draw order: cluster boxes (outermost first), edges, then leaf nodes and their labels.

Call at the end of each frame.

Get the current eraser path for rendering.

Use HSL: keep hue/sat from shade_25, push lightness higher (toward shade_50->25 trend).

Exit text editing mode.
