    Component: Line
    Renders one laid-out line as three regions: a fontA bulk run (past the
-    slider), an N-char crossfade window straddling it, and a fontB bulk run (not
+    slider), a crossfade window straddling it (its size derived per line from
+    the line's grapheme count via `windowSizeForLine`), and a fontB bulk run (not
    yet past). Bulk runs are native shaped text (kerning, ligatures); only the
    window uses per-char DOM. `split` is a primitive so the render-model
    `$derived` skips recomputation on ticks that leave it unchanged.
