v0.57.0

Comments on a handbook page work now. They never showed up, whatever you set: no shipped layout contained a comment block, and the import closed comments on every page it created. Open them under the page's Discussion panel and they appear.

Mermaid diagrams follow your theme instead of always drawing light, so the connecting lines stay visible on a dark theme. An imported diagram keeps the title and description it carries (accTitle and accDescr), so screen readers get a description instead of the diagram source.

The Custom CSS field no longer lets a pasted snippet load fonts or images from a foreign server. Anonymous feedback is capped at 200 votes per page and hour. An export bundle now carries the reviewer's user name instead of their e-mail address.

The German translation covers the appearance settings, which reached a German site in English since 0.56.0.

Nothing needs doing on update; pages keep the comment setting they have.
