 * Parity fix: title/half-title pages are block/top-flow in the EPUB, print and
 * book preview (title starts ~2em from the top, per each preset's title-page
 * architecture) -- not vertically centred. The generic display-page rule above
 * centres them, which broke parity with everywhere else. Keep the genuinely
 * centred display pages (dedication, praise, also_by, ...) flex-centred; render
 * title pages block so the preset-editor preview matches the real output.
