Inline comments:
In `@cmuxTests/FilePreviewTextEditorTextKitTests.swift`:
- Around line 80-82: Add a Cmd-0 key-event assertion to the configured-font test
around zoomPreviewFontIn and resetPreviewFontSize, verifying that an editor
configured with a 17-point font resets to
GlobalFontMagnification.scaledSize(17), rather than only invoking
resetPreviewFontSize directly. Keep the existing direct reset and tolerance
check intact.
- Around line 71-78: Add an assertion alongside the existing textStorage
paragraph-style check to validate textView.typingAttributes[.paragraphStyle] as
an NSParagraphStyle with lineHeightMultiple approximately 1.5, preserving
coverage for both existing and newly typed text.
In `@Sources/Panels/FilePreviewFontSizeSettings.swift`:
- Around line 4-31: Replace the static-only FilePreviewFontSizeSettings and
FilePreviewLineHeightSettings namespaces with constructable, injectable owner
types. In Sources/Panels/FilePreviewFontSizeSettings.swift lines 4-31, move
UserDefaults access and related behavior onto an instance owner while preserving
the existing constants, clamping, defaults resolution, and persistence behavior.
Apply the same pattern in Sources/Panels/FilePreviewLineHeightSettings.swift
lines 4-33, preserving its test injection support.
- Around line 20-24: Update resolvedDefault in
Sources/Panels/FilePreviewFontSizeSettings.swift at lines 20-24 to reject
persisted Boolean NSNumber values, then clamp and round valid font sizes to
whole points; update resolvedDefault in
Sources/Panels/FilePreviewLineHeightSettings.swift at lines 20-24 to reject
Boolean values before applying the multiplier clamp.
In `@web/messages/da.json`:
- Line 1040: Update the Danish translation values at the entries around lines
1040 and 1066, replacing “Linjehøjemultiplikator” with “Linjehøjdemultiplikator”
while preserving the rest of each value.

Greptile SummaryThe PR adds configurable font family, font size, and line height throughout the native file-editor settings, configuration parser, editor runtime, schema, documentation, and locale catalogs. The native typography catalog additions still omit locales already supported by the touched catalog.
Confidence Score: 4/5The PR is not ready to merge because the new native typography controls and search aliases remain untranslated in catalog-supported locales beyond English and Japanese. The current catalog entries still provide only English and Japanese values, so users in other supported native locales receive fallback UI text and cannot search using localized typography terms.

existing localized title behavior.

zoom, matching the terminology used by the related translation and reset
behavior.

of scrolling horizontally.

The native-locale disagreements follow the repository localization contract: new native Resources/Localizable.xcstrings keys are en/ja, while web/messages/*.json carries the broader locale set.
CI/review state at this audit: an earlier run for this exact head passed (CLA policy guard run 33572269091; CLA Assistant run 33572269060), but the newest attempts (CLA guard run 33572436741 attempt 2 and CLA Assistant run 33572436894 attempt 2) failed in the GitHub API lookup path under the repository-wide rate limit (Could not query the pull request / generic policy rejection), and their exact reruns failed the same way. Testbox, Socket, and Vercel-comment checks are green; the active branch ruleset requires CLA policy guard, so the latest required context is not green. A human approval is also now required; @lawrencecchen is requested and GitHub reports REVIEW_REQUIRED. Vercel preview contexts remain pending in the integration queue (advisory).
No local build, reload, xcodebuild, or E2E workflow was run because the continuation explicitly forbids launching any build; the AWS workspace had no current-head artifact to exercise without starting one. Consequently no current-head end-to-end app verification exists. The PR is intentionally not merged, and issue #10319 remains open pending a successful required-check rerun, human approval, and separately authorized runtime verification.

The native-locale disagreements follow the repository localization contract: native Resources/Localizable.xcstrings additions are English/Japanese in this feature PR, while web message catalogs carry the broader locale set.

Closes #10319
Summary
The built-in text editor always rebuilt its font from a hard-coded 13-point monospaced system font, and it never supplied paragraph styling. That made Markdown preview typography disappear whenever a panel switched into edit mode.
This change adds the
fileEditor.fontFamily,fileEditor.fontSize, andfileEditor.lineHeightsettings alongside the existingfileEditor.wordWrapsetting. Config parsing, the typed settings catalog, Settings UI, schema/docs, and all web locale catalogs now expose the keys. The TextKit 1 editor resolves installed AppKit families with a monospaced fallback, uses the configured size as the per-editor zoom reset baseline, reapplies global magnification, and appliesNSParagraphStyle.lineHeightMultipleto existing and newly typed text. Markdown edit mode and ordinary file previews share the same path.Verification

Closes #10319. Makes the built-in plain-text editor's font family, size, and line height configurable, replacing the fixed 13-point monospaced system font and restoring Markdown preview typography in edit mode. Cmd-0 now returns each editor to the configured baseline without clearing explicit zoom overrides.
fileEditor.fontFamily,fileEditor.fontSize, andfileEditor.lineHeightto Settings UI/search, config parsing, schema/docs, and localized strings; no migration required.Written for commit 86f9484. Summary will update on new commits.

Overview
Adds
fileEditor.fontSize,fileEditor.fontFamily, andfileEditor.lineHeightas first-class settings (catalog, App settings UI, search/deep links,cmux.jsonimport/template, JSON schema, and docs/locales), alongside existing file-editor options.The plain-text
FilePreviewTextEditornow reads those values via@AppStorageon the text view (word wrap moved here too) so Settings edits do not invalidate unrelated surfaces like the Markdown WebView.SavingTextViewapplies family/size/line-height live, treats the configured size as the Cmd-0 zoom baseline while keeping per-editor zoom overrides, and syncs content reloads under a delegate guard so typography updates do not publish stale text.New persistence helpers clamp/quantize values; tests cover resolution, config import, paragraph-style preservation, and zoom behavior.
