Preview overlay and editorial ordering

Preview overlay

A preview link composes the change set over published content, so a list page in preview renders the whole site rather than the handful of entries being edited. Updates replace their published version, creations appear, unpublished and deleted entries disappear, and everything untouched stays. Ordering, filtering, and pagination apply to the composition.

$ myna preview create chs_01...

Reading in scoped mode returns only what the change set touched, for diff views.

Editorial ordering

Collections can carry an editorial order.

$ myna entries reorder posts --move ent_01... --after ent_01...

Ranks are fractional, so moving one entry writes one row. Order is arrangement rather than content: it carries no revision, is not staged on a change set, and reaches readers immediately. That is why a reorder is confirmation-gated rather than staged.

CORS check

myna cors check reports why a browser request from a given origin would be rejected — the project's public API setting, the collection's visibility, and the configured origins, each as a separate verdict.
