+   * instead of the padded pill every other collapsed chip draws. Floored at zero it
+   * fills exactly the rail, and the avatar keeps the same 8px offset as the help
+   * glyph above it.

    * The name is the button's accessible name — no `aria-label`, which would
    * override the visible text. Radix contributes the menu role and expanded state.
