+Persian, Arabic and Hebrew now read right to left in the Response Viewer and in the File Viewer's markdown view (#715). Each paragraph, heading, list, quote and table takes its direction from its own first letter, so a right-to-left answer is right-aligned with its punctuation, list bullets and quote bar on the right, while an English paragraph beside it stays left to right. Code blocks, inline code and file paths stay left to right and no longer decide a sentence's direction, so a Persian sentence that starts with `npm install` still reads right to left. The phone's Compose dialog lays a right-to-left prompt out the same way. The terminal pane is unchanged: xterm.js has no right-to-left support yet (xtermjs/xterm.js#701).

+/**
+ * @fileoverview Right-to-left text in rendered markdown (`CodemanApp._renderMarkdown`, issue #715).
+ *
+ * The Response Viewer and the File Viewer's markdown view rendered every block left to
+ * right, so a Persian, Arabic or Hebrew answer was left-aligned, its punctuation landed on
+ * the wrong end and its list markers sat on the left. `_renderMarkdown` now gives each
+ * OUTERMOST prose block `dir="auto"` (the browser picks the direction from the block's own
+ * first letter) and pins code to `dir="ltr"`, which also keeps a code span from deciding a
+ * sentence's direction, since `dir="auto"` skips descendants that carry a `dir`.
+ *
+ * jsdom does not resolve `dir="auto"`, so this pins the attributes the browser acts on;
+ * what Chromium makes of them was checked by eye when the change was made.
+ *
+ * Drives the SHIPPING artifacts (vendored `marked`, vendored DOMPurify + `sanitize-html.js`,
+ * `constants.js` and `app.js`) in a `vm` with a jsdom document, the technique from
+ * response-viewer-external-links.test.ts. No port / server needed.
