+> work, no infra change). Native drag-and-drop reorder for sections + entries (keyboard arrows kept).
+> Per-item editing via `GET /api/cv/outline`: hide, title/subtitle override, rich-text bullets
+> (`**bold** *italic* __underline__ [link]`, escaped-then-whitelisted server-side). `ItemOrder`
+> reorders entries without touching the master profile. Preview: zoom presets, measured page count +
+> page navigation + page-break indicators, "updating" state. Unsaved/Saving/Saved indicator, loading
+> skeletons, better empty states, ATS-friendly theme badge, a11y (ARIA labels, keyboard theme cards,
+> focus rings), print-quality page-break CSS, AA contrast fix. Docs: `cv-builder.md`,
+> `cv-theme-engine.md`. **Still open:** PDF page-number footer (Playwright `footerTemplate`);
+> client-side preview (kept server-rendered for fidelity); `ProfileCvController` split.
