@openpresentation/opf-editor 0.22.0

• RR-93: table cells take a bold style, so a number cell can be bold without rich runs, which dropped the column's number format and alignment. setTableCellStyle(editor, tablePath, cell, { bold: true }) sets it (null removes it, a non-boolean is refused), a table style keeps it, and the design panel's table section has a Bold checkbox beside the cell fill and alignment. Needs core 0.22.0 (TableCellStyle.bold); the core floor is now ^0.22.0.
• RR-95: README note that the chart options panel edits highlight as its only color-related setting and the editor has no chart.colors control yet (a known gap); chart.colors is set in the document directly.
• RR-87: the example playground forwards a refused canvas commit to autosave, so an invalid active draft reports a persistence error and still warns before leaving even when the stored document is unchanged. This changes the example host integration only; library APIs and npm payloads are unchanged.
