* This module approximates browser-like soft wrapping for Excalidraw text.

* 2. `getWrappedTextLines()` reflows each hard line into one or more visual lines and
* records where each visual line came from in the source text.
* 3. `wrapLine()` assembles tokens into lines, and `wrapWord()` handles a single token
* that is wider than the available width.
* 4. `trimLine()` / `trimLineEndAtSoftBreak()` mirror browser behavior around trailing
* whitespace so the rendered text stays consistent with what users see on canvas.
*
* Mostly, you'll want to use wrapText(). getWrappedTextLines() is for callers
* that need metadata such as mapping visual lines back to `originalText`
* for caret placement or future editor features.
