+Character Styles menu New/Redefine and footer New capture the first selected character of a nonempty Type selection, including exact style-run and UTF-8 boundaries; New adds a definition without applying it. New/Redefine commands accept optional `end` for range capture. Start-only command affinity, existing UI caret/object behavior and paragraph capture at `start` remain unchanged. Pointer regressions assert captured definitions, linked-text updates and local overrides, complete-document Undo/Redo and saved state, with whole-object, collapsed-caret and range-Apply controls. Capture closes prior typing while preserving the Type selection. Live text and Select All regressions exercise menu New/Redefine and footer New, asserting that further typing retains the captured definition and that typing, capture and further typing have separate Undo/Redo steps. Focused engine and egui input tests pass for boundary capture, all three live-typing capture routes and the existing compatibility controls. Full workspace CI passes.

 ## Revision history
 
 | Date | Change | Summary |
 |---|---|---|
 | 2026-10-13 | minor | Paragraph/Properties alignment buttons show mixed alignment without changing range commands; headless regressions, full integration CI and visual review pass; other mixed paragraph fields, scores and hours unchanged |
 | 2026-10-13 | minor | The font scan on Linux also reads the folders fontconfig's configuration lists, such as TeX fonts under `/usr/share/texmf/fonts` (#1548, fixes #1529; not verified on Linux); scores and hours unchanged |
+| 2026-10-13 | minor | Character Styles range capture samples the first selected character at run boundaries and closes prior typing; boundary and typing-history input tests and full workspace CI pass; lifecycle and range controls retained; scores and hours unchanged |
 | 2026-10-13 | minor | The commands that make or restyle type, and MCP `add_text`, report area type that does not fit its frame, and `add_text` takes Auto Size and Shrink Text to Fit (#1500, fixes #1471); a tab stop in the Tabs panel drags from where the press landed, a stop just added included (#1487, fixes #1458); scores and hours unchanged |
 | 2026-10-13 | minor | Fit Headline no longer pushes the tracking to its ceiling and loses glyphs when the frame holds one line (#1445, fixes #1444); text frames, wrap shapes and type paths with coordinates beyond a billion points hold no text, and layout limits its search for room, instead of hanging (#1451); scores and hours unchanged |
 | 2026-10-12 | minor | Character styles retain explicit Auto leading, propagate resets and preserve local leading overrides; scores and hours unchanged |
