Character Styles: Advanced Character Formats takes scales and baseline shift up to the document limit

Horizontal Scale and Vertical Scale accept any number above 0 and at most 4000000 %, and Baseline Shift accepts -4000000 to 4000000 pt, the limits the document model keeps a character style in. Character Rotation is stored from -180 to 180 degrees, as text.setFormat stores it. A scale outside its limit shows the new message "{label} must be a number above 0 and at most {max}", translated in every catalog that has Basic Character Formats.

 - **OpenType SVG colour fonts:** each glyph's SVG document is read by the SVG importer (registered by the engine) into vector art in the run's colours, then drawn, exported and outlined as COLR glyphs are; PDF real text writes them as text that draws nothing and draws their art where they sit.

 - **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.

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.

 - **Text styles redefined to the defaults:** New and Redefine Character Style and Paragraph Style capture every attribute of the selected text, including those at their defaults (Auto kerning, Roman baseline alignment, the default Hyphenation options, the Every-line Composer, no tab stops), and `charStyle.setAttrs` and `paraStyle.setAttrs` keep an attribute set to its default value. After a redefinition, text whose value still equals the old definition's takes the new value, a default included; local overrides stay, and text that still has the old value of an attribute the new definition leaves out goes back to the Normal style's value. The style panels show "+" only where the text differs from its style, including type with Auto alignment.
