 * underline renders as a single uniform weight across text and tab characters,
 * matching Word, on any display density (SD-3330). The divisor approximates the
 * font's natural underline weight (≈ what `text-decoration-thickness: auto`
 * produces) while staying deterministic across platforms.
 *
 * Rounded to an integer px because CSS borders snap to integer device pixels
 * while `text-decoration-thickness` keeps fractional values; using an integer
 * makes the tab border and the text underline rasterize to the same line weight.
