WalkthroughThis PR refactors the CSS editor component from an imperative ref-based API to a controlled component pattern, adds TypeScript ambient module declarations for Prism virtual imports, and updates development dependencies. The refactoring introduces state-driven data flow with loading and cancellation logic while simplifying component prop interfaces. Changes

54-89: Consider using AbortController for proper request cancellation.The
isCancelledflag prevents state updates after unmount, but the HTTP request continues in the background. Per thegetCSSContentsAPI signature (which acceptsRequestOptionswith an optionalsignal), you can pass anAbortSignalto actually cancel the in-flight request.♻️ Suggested improvement with AbortController
useEffect(() => { - let isCancelled = false; + const abortController = new AbortController(); async function fetchServerCSS() { // check for isOpen to fetch recent css if (isOpen) { try { setError(null); setIsLoadingCss(true); - const css = await getCSSContents(); - if (isCancelled) { - return; - } + const css = await getCSSContents({ signal: abortController.signal }); setSavedCss(css); setDraftCss(css); } catch (_error) { - if (isCancelled) { + if (abortController.signal.aborted) { return; } setSavedCss(''); setDraftCss(''); setError('Failed to load CSS from server'); - /** no error handling for now */ } finally { - if (!isCancelled) { + if (!abortController.signal.aborted) { setIsLoadingCss(false); } } } } fetchServerCSS(); return () => { - isCancelled = true; + abortController.abort(); }; }, [isOpen]);🤖 Prompt for AI Agents

15-16: Consider reordering: function declaration before export.The
export default memo(CodeEditor)appears before the function declaration. While this works due to JavaScript hoisting, it's unconventional and may confuse readers expecting the definition before its use.♻️ Suggested reorder

- Around line 40-50: handleSave currently swallows errors from postCSSContents;
update it to capture the thrown error in the catch block and set an error state
(e.g., setSaveError or similar) so the UI can surface the failure to the user,
keep setSaveLoading behavior in finally, and ensure setSavedCss(draftCss) only
runs on success (i.e., after awaited postCSSContents resolves); reference
handleSave, postCSSContents, setSaveLoading, setSavedCss and add/use a
setSaveError state setter to store and display the error message.

Loading the CSS editor caused a reflow and sometimes a page refresh
