New export target: a single offline .html rendered from the deck's Marp
Markdown. Bundles (inlines) marked, highlight.js, MathJax (tex-svg, no font
files) and mermaid, so code highlighting, LaTeX math and mermaid diagrams all
render in any browser with no network access.
- MarpHtmlService splits the deck on `---`, strips front-matter, and inlines
the vendored libraries (assets/web_export/) with a </script> breakout guard.
The asset loader is injectable for testing.
- ExportFormat.html wired through ExportService (no rasterization needed),
the export dialog (new button, skips slide rendering) and app_shell
(passes the generated Markdown). Export dialog is now scrollable.
Note: rendered with marked, not Marp Core, so theme fidelity differs from the
in-app preview / PDF / PPTX; the win is a portable, dependency-free deck.
Tests: slide splitting, library inlining, breakout escaping, and an
end-to-end .html export.

Privacy: replace the runtime google_fonts fetch with a locally bundled
EB Garamond (variable TTFs + OFL license), so the app no longer contacts
Google's servers. Removes the google_fonts dependency.
PDF export:
- Add a normal/compressed image-quality choice in the export dialog.
Compressed re-encodes slides as JPEG (q60) at 1280px for a small handout,
saved as a separate "-compact" file.
- Add a configurable export directory (Settings → Exportmap); when unset,
exports land next to the deck as before.
- Prefix every export with a UTC timestamp (YYYYMMDDHHMMSS) so exports sort
chronologically and never overwrite each other.
Tests: export service (compression, output dir, timestamp) and an export
dialog widget test asserting the quality choice renders.
