// === lane additions ===
// Later F-series lanes may append one window export assignment per line below.
// Do not edit anything above this marker.
// F-06: window.onEvent is assigned by bootWs() in features/ws (imported from main.tsx).
// F-07: window.t / window.tOptional are assigned by the i18n module.
// F-10: window.openConversation / down assigned by features/messages.
// F-13: fetchAllMessages / fetchOlderMessages / fetchRecentMessages /
//   renderMessageRefChips / renderComposerRefChips / hint assigned by
//   features/sessions. Both lanes ported openConversation and the fetch
//   trio independently; integration split them so each name has one owner
//   (main.tsx imports sessions before messages, so a shared name would
//   have been silently overwritten rather than reported).
// F-14: window.highlightTraceback / window.notebookExportLink are assigned by features/notebook (imported from main.tsx).
// F-15: timeline contract names plus loadWorkbenchState are assigned by
// features/timeline (imported from main.tsx).
// F-17: window.parseTable / window.renderSheet are assigned by bootArtifacts() in features/artifacts.
// F-19: window.openCust / window.custTab / window.telemetryRow are assigned by bootCustomize() in features/customize.
// F-20: window.openModalEl / closeModalEl / trapModalKeydown / openPalette /
// closePalette / applyLayout / setLayout / uploadFiles / micDictate / loadNotes
// are assigned by bootChrome() in features/chrome (imported from main.tsx).
// F-12: window.ac / edacTeardown / bindEditorAutocomplete are assigned by
// features/autocomplete (imported from main.tsx).
// F-11: window.send / buildStepCard / renderAttachmentProblems /
//   renderRefProblems / searchResultHttpUrl / admissionSettled /
//   forgetAdmission / outstandingAdmissions / reconcileLastAdmission /
//   rememberAdmission are assigned by features/send (imported from main.tsx).
// F-16: window.buildExecutedCodeView / execSourcesState / selectExecFrame /
//   toggleExecutedCode / showProvenance / renderProvenanceInto /
//   renderNotebook are assigned by bootExecution() in features/execution.
// M-01: first-run wizard is mounted by bootOnboarding() in features/onboarding.
// F-18: window.molecule / renderAnnotatableImage / annotationStatus /
//   annotationIsHeld / openAnnotations / loadAnnotations / renderPins /
//   openPinPop / openKetcher / renderLocatorComments assigned by
//   bootIslands() in islands (imported from main.tsx).
