 * Japanese line breaking shared by every public page.

 * Japanese headings must not use English word-wrapping assumptions. Strict
 * kinsoku rules keep punctuation in the right place; balanced wrapping avoids
 * leaving one or two characters on a final line. Browsers that support phrase
 * segmentation get the stronger auto-phrase behaviour progressively.
