 - **Character-style Auto leading:** capture and explicit style attributes retain Auto as a reset, distinct from omitted leading. Redefine and later numeric updates preserve local leading overrides; the Character Styles marker recognizes Auto correctly. Regression assertions cover partial definitions, Undo/Redo and native save/load serialization. Public references: [Character and paragraph styles](https://helpx.adobe.com/illustrator/using/character-paragraph-styles.html) and [Leading](https://helpx.adobe.com/illustrator/using/line-character-spacing.html).
 - **Character-style numeric bounds:** `charStyle.new`, `charStyle.edit`, and `charStyle.setAttrs` accept size from 0.1 to 1296 pt, explicit leading from 0.1 to 5000 pt, horizontal and vertical scale from 1% to 10,000%, and baseline shift and Tate-chu-yoko offsets from -1296 to 1296 pt. Out-of-range input leaves the style and Undo history unchanged; Auto leading remains available. These limits match the Character panel controls.
 - **Character Style Options, General and Basic Character Formats:** the dialog edits a style's name and stored character formats together. Empty fields remain unset, checkboxes show an indeterminate unset state, Basic's Reset Panel clears its explicit settings, and Preview can be canceled without changing history. OK saves one undo step; New Character Style offers the same fields from captured text or the interface language's defaults without a selection.

A single click still applies the style, the second click of the double-click does not apply it again, and the built-in Normal style opens no dialog. Test `panels::text_styles::tests::double_clicking_a_character_style_row_opens_its_options`.
 - **Character Style Options window size:** the dialog keeps a fixed width wide enough for the widest tab's controls and scrolls its sections inside a window shorter than them, so it stays on screen and its OK and Cancel buttons stay visible; the width is the same in every section and the height follows the section. Test `dialogs::char_style_options::tests::the_sections_scroll_in_a_window_shorter_than_the_general_list`.
