Shell.tsx had grown to about 8,000 lines, roughly 2,200 of them module-level
components and helpers below ShellPage. That made the page hard to navigate
and review and turned every chat change into an edit of one hot file.
This is a move-only refactor: code is moved verbatim and only imports and
exports change. No renames, no JSX or memo boundary changes.
- shell/transcript.tsx: Transcript, QuoteSelectionButton, MessageHoverActions,
MessageView
- shell/composer.tsx: Composer, slashActionLabel, MentionOptionIcon,
MentionChipIcon, ATTACHMENT_ACCEPT
- shell/computer-screen.tsx: ComputerReleaseActions, embeddableScreenUrl,
screenIframeSandbox, DesktopKindEmptyState, computerPlaceholder,
computerLabel (all used by the computer pane)
- shell/thread-state.ts: threadSnapshotSignal, firstThreadRoute,
applyThreadEvent, newClientNonce
- shell/roster-format.ts: stripSpaceTitlePrefix, formatRosterTime,
cleanRosterPreview
- shell/message-preview.ts: previewMessageText (shared by composer and
transcript)
- shell/collapsed-sidebar-sections.ts: collapsed sidebar storage helpers
- shell/shell-types.ts: PendingAttachment and FALLBACK_BOT_COLOR, shared by
Shell.tsx, composer and transcript
Types, constants and one-off helpers used only by ShellPage stay in
Shell.tsx. The Lingui catalogs only change their file-reference comments;
message ids and translations are unchanged.
