Conversation
…pt on web Two Settings -> Appearance defects in the session transcript: - Text Size (uiFontScale) never applied to transcript markdown on web. Web Unistyles registers style values as non-enumerable, non-writable data properties; scaleTextStyle's clone kept those descriptors, the scaling assignment threw, and the fail-closed catch returned the original style. buildEnrichedMarkdownStyle then read the unscaled fontSize back off the raw object, pinning all markdown metrics at their 16px base regardless of the setting. scaleTextStyle now redefines numeric metrics on the clone (preserving enumerability so CSS-class-driven text rendering is untouched) and only fails closed for non-configurable metrics. - Content Width (uiContentWidthMode) only applied after a reload. Transcript row caps read the static layout.maxWidth getter inside Unistyles stylesheets, which evaluate once at registration. The transcript row owners (MessageView, ToolCallsGroupRow, ToolCallsGroupUnitRowFrame, PendingMessagesTranscriptBlock) now apply the reactive useLayoutMaxWidth() value, matching the already-reactive ChatListInternal/ChatHeaderView/ItemGroup consumers. Both proven RED->GREEN: scaleTextStyle and buildEnrichedMarkdownStyle against the exact web-Unistyles property shape, and a content-width component test verified failing on HEAD before the fix.
Greptile SummaryThe PR fixes transcript appearance settings by safely scaling numeric text metrics stored in web Unistyles descriptors and by replacing registration-time transcript width caps with reactive values.
Confidence Score: 5/5The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking issue identified. The descriptor-aware scaling preserves original style objects and renderer-relevant enumerability, while the width changes follow the existing reactive layout-hook pattern and include focused regression coverage.

Summary
Settings → Appearance has two defects on the session transcript, both reported on the web app:
uiFontScale) never applies to transcript markdown on web — not even after a reload.uiContentWidthMode) only applies to the transcript after a browser reload, while other surfaces (settings screens, headers, item groups) update instantly.Root causes
Text Size — a property-descriptor interaction between web Unistyles and the font-scaling helper:
react-native-unistyles/src/web→removeInlineStyles), with the secret under an enumerableunistyles_*key that does not carry the nativeuni__getStylesshape.scaleTextStyleclones the style preserving descriptors, so the scaling assignment (next.fontSize = …) throws on the non-writable clone in strict mode, and the fail-closedcatchreturns the original, unscaled style.buildEnrichedMarkdownStyle'sflattenTextStylereturns the raw object, so the unscaledfontSize: 16is still readable via property access and wins over the would-be scaled fallback (16 × uiFontScale). Every markdown metric derives from that base → the whole transcript is pinned at 16px.useWebUiFontScale) can't compensate: it scales.unistyles_*class rules, but the enriched markdown renderer emits inline pixel styles built from the poisoned base.Content Width — the transcript row caps read the static
layout.maxWidthgetter insideStyleSheet.create, which Unistyles evaluates once at registration, so no re-render can refresh them. The surrounding list/header already use the reactiveuseLayoutMaxWidth(), which is why only the per-row cap (the narrower constraint) appeared dead until reload.Fix
scaleTextStylenow sets scaled numeric metrics on the clone viadefinePropertywhen the original property is non-writable or accessor-based, preserving enumerability so CSS-class-driven text rendering (and the existing override sheet) are unaffected. It still fails closed for genuinely non-configurable metrics. The enumerableunistyles_*secret is carried over unchanged, so className-based rendering keeps working.MessageView,ToolCallsGroupRow,ToolCallsGroupUnitRowFrame(toolCallsGroupChrome), andPendingMessagesTranscriptBlock— now apply the reactiveuseLayoutMaxWidth()value instead of the frozen stylesheet cap, matching the already-reactiveChatListInternal/ChatHeaderView/ItemGroupconsumers.Tests (RED → GREEN)
uiFontScale.test.ts: new case for the exact web-Unistyles property shape (non-enumerable/non-writable metrics +__uni__keysecret) — scaled values readable, enumerability preserved, secret reference kept, original not mutated. Failed before the fix (helper returned the original unscaled object).useEnrichedMarkdownStyle.test.ts(new): composed contract — transcript markdown metrics scale from both a plain and a web-UnistylestextStyle, and stay unscaled at scale 1. The web-shape case failed before the fix (paragraph pinned at 16 instead of 20.8).toolCallsGroupChrome.contentWidth.test.tsx(new): the row frame's width cap follows auiContentWidthModechange without remount (850 → ∞), following the existing*.contentWidth.test.tsxpattern. Verified failing against the unfixed component (frozen at 850) and passing after.Validation

The frozen-
StyleSheet.create+layout.maxWidthpattern also exists on a handful of non-transcript surfaces (SessionsList,InboxView,FriendsView,ProfileEditForm,ToolFullView,SettingsActionFooter,ApprovalDetailScreen, some prompt/MCP screens). Those only surface when navigating to an already-registered screen after changing the setting without a reload; left for a follow-up rather than widening this PR.Implemented with Claude (AI), directed by @hubikj.
