VictorandClaude Opus 5.5 6190525482 G4: Paragraph panel menu › Roman Hanging Punctuation
The Paragraph panel menu's Roman Hanging Punctuation was a disabled stub.

It is now a per-paragraph attribute: in a left-to-right paragraph of point
or area type with it on, the punctuation Optical Margin Alignment hangs
(quotation marks, hyphens, full stops and commas wholly; asterisks,
tildes, ellipses, en and em dashes, colons and semicolons by half) hangs
outside the margin when it starts or ends a line, on the same sides
(left-aligned lines at their left, right-aligned at their right, centered
and justified at both); letters don't hang. With Optical Margin Alignment
on as well, letters hang too. East Asian punctuation keeps hanging only
through burasagari. The layout shares Optical Margin Alignment's hanging
code, given the share of each glyph that hangs.

text.setFormat takes romanHangingPunctuation; it is off by default, saved
only when on, carried by paragraph styles (New and Redefine capture it)
and turned off by Reset Panel. The panel menu item is a checkbox enabled
with type selected.

Docs: docs/mcp.md, docs/type-parity.md, docs/gaps.md.

Closes #2756.

//! Character Styles and Paragraph Styles panels.
//!
//! A style is a named, partial set of attributes ([`TextStyleDef`]); text using it records the
//! name in `CharStyle::style_name` / `ParaStyle::style_name`. Applying a style sets its attributes
//! (Clear Overrides first resets to the Normal style). Redefining a style updates its users but keeps
//! their local overrides: an attribute changes only where it still had the old style's value.
