The Export context-menu offered only md↔docx↔html (a symmetric set), so PDF — which the server supports only as md→pdf — was missing. The markdown editor's DOCX/HTML/PDF buttons hardcoded their own list, so the two could drift. Introduce a single source of truth in download.js: EXPORT_MATRIX mirrors zddc/internal/convert.Convert() exactly (md→docx|html|pdf, docx→md|html, html→md|docx), exposed as download.exportTargets(ext) + download.convertUrl(). The Export submenu and the editor's buttons both consume it, so a .md file now offers PDF in the menu and the two surfaces can never disagree. PDF stays markdown-only (no docx→pdf / html→pdf path exists server-side). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
