readme/readme_zh gain Typography and verbatim-protection sections
(alignment, hanging punctuation, parshape/first-line indent,
no-break characters, halfwidth kinsoku) plus the honest limitation
notes (mid-line CLREQ compression and left protrusion are not
renderable in Emacs). DEVELOPER/DEVELOPER_ZH document the break-
permission layer, alignment extra-stretch, protrusion lockstep and
per-line specs (§5.1) and the C 1.4 API surface.
