 - ([#13775](https://github.com/quarto-dev/quarto-cli/issues/13775)): Fix brand fonts not being applied when using `citeproc: true` with Typst format. Format detection now properly handles Pandoc format variants like `typst-citations`.
 - ([#13868](https://github.com/quarto-dev/quarto-cli/issues/13868)): Add image alt text support for PDF/UA accessibility. Alt text from markdown captions and explicit `alt` attributes is now passed to Typst's `image()` function. (Temporary workaround until [jgm/pandoc#11394](https://github.com/jgm/pandoc/pull/11394) is merged.)
 - ([#13870](https://github.com/quarto-dev/quarto-cli/issues/13870)): Add support for `alt` attribute on cross-referenced equations for improved accessibility. (author: @mcanouil)
+- ([#13878](https://github.com/quarto-dev/quarto-cli/issues/13878)): Typst now uses Pandoc's skylighting for syntax highlighting by default (consistent with other formats). Use `syntax-highlighting: idiomatic` to opt-in to Typst's native syntax highlighting instead.
+- ([#13879](https://github.com/quarto-dev/quarto-cli/pull/13879)): Add Tufte-style margin layout for Typst using the marginalia package. Supports `.column-margin` for margin notes, figures, tables, and captions; `.column-screen` and `.column-page` for full-width content; `citation-location: margin`; `reference-location: margin` for sidenotes; `suppress-bibliography`; `cap-location: margin`, `fig-cap-location: margin`, and `tbl-cap-location: margin`; `grid` options (`margin-width`, `body-width`, `gutter-width`); and `margin-geometry` for fine-grained layout control.
 - ([#13917](https://github.com/quarto-dev/quarto-cli/issues/13917)): Fix brand logo paths not resolving correctly for Typst documents in project subdirectories. Brand logo paths are now converted to project-absolute paths before merging with document metadata, replacing the fragile `projectOffset()` workaround.
 - ([#13942](https://github.com/quarto-dev/quarto-cli/issues/13942)): Fix Typst compilation errors showing confusing internal stack traces. Users now see only the relevant Typst error message.
 - ([#13950](https://github.com/quarto-dev/quarto-cli/pull/13950)): Replace ctheorems with theorion package for theorem environments. Add `theorem-appearance` option to control styling: `simple` (default, classic LaTeX style), `fancy` (colored boxes with brand colors), `clouds` (rounded backgrounds), or `rainbow` (colored start border and colored title).
 - ([#13954](https://github.com/quarto-dev/quarto-cli/issues/13954)): Add support for Typst book projects via format extensions. Quarto now bundles the `orange-book` extension which provides a textbook-style format with chapter numbering, cross-references, and professional styling. Book projects with `format: typst` automatically use this extension.
 - ([#13978](https://github.com/quarto-dev/quarto-cli/pull/13978)): Keep term and description together in definition lists to avoid breaking across pages. (author: @mcanouil)
-- ([#13878](https://github.com/quarto-dev/quarto-cli/issues/13878)): Typst now uses Pandoc's skylighting for syntax highlighting by default (consistent with other formats). Use `syntax-highlighting: idiomatic` to opt-in to Typst's native syntax highlighting instead.
 - ([#14126](https://github.com/quarto-dev/quarto-cli/issues/14126)): Fix Skylighting code blocks in Typst lacking full-width background, padding, and border radius. A postprocessor patches the Pandoc-generated Skylighting function to add `width: 100%`, `inset: 8pt`, and `radius: 2pt` to the block call, matching the styling of native code blocks. Brand `monospace-block.background-color` also now correctly applies to Skylighting output. This workaround will be removed once the fix is upstreamed to Skylighting.
 - ([#14202](https://github.com/quarto-dev/quarto-cli/issues/14202)): Fix CSS inlining (`juice`) failing on Windows when Quarto is installed in a path with spaces (e.g., `C:\Program Files\Quarto\`).
