Browser Font Scope

A focused probe for the Layoutmaster browser runtime: the same CSS font stack is painted once by native DOM text and once from solved Layoutmaster pieces.

Pieces-
DOM height-
Master height-
Font stateIdle
Browser-owned fonts

Layoutmaster measures with the page's browser font machinery and does not expose a font-loading API.

Fallback stays native

Mixed scripts rely on the environment's fallback chain instead of a custom Unicode-range map.

Pieces stay literal

The right pane paints returned pieces as-is, including bidi punctuation and browser-shaped fallback runs.

Native Browser DOM

The browser lays out one normal text box.

Layoutmaster Pieces

Layoutmaster lays out once; the DOM paints returned pieces.
