Select a standalone image to align it left, center, or right. The choice stays with that image through save, Markdown edits, and reload. Existing images keep their previous layout until an alignment is chosen. Galleries keep their own layout. Native editors apply a saved alignment and do not add a picker in this change.
Nested outline rows now indent 12px per level, so deep headings keep more text in the 300px panel. Hierarchy guides sit on the disclosure-button center and follow the theme root font size. Full-row highlight, collapse, and heading jumps stay the same.
