Add 51 OFL-1.1 Latin font files (16 families, ~19.5 MB) for SlideCraft and other presentation/document apps, listed in a new opt-in manifest, fonts/latin-manifest.txt, with the same format as fonts/manifest.txt. fonts/manifest.txt is unchanged, so apps that embed it ship the same fonts. - Inter (v4.1 release statics), Carlito, Caladea, Liberation Sans/Serif/Mono (2.1.5), Source Sans 3 (3.052R), Source Serif 4 (4.005R), Montserrat, Lato, Open Sans, Roboto, Merriweather (SorkinType statics), Playfair Display, Poppins, Nunito Sans; google/fonts files pinned at 7085eb8. - craft-fonts: LATIN_FONTS table, load_latin/load_manifest, embed-latin feature. - craft-fonts-tests: checksum, licence and family-name tests cover both manifests; new tests for Western European coverage, outlines, and that "Variable" styles (and only those) are variable fonts with italic bits matching the style. - docs/integration.md: how an app opts in; web builds embed only Inter Regular + Bold from it. README, ATTRIBUTION and CI updated. Co-Authored-By: Claude Opus 5.5 <[email protected]>
craft-fonts
Reusable fonts for the Crafting Apps.
This library is meant to have the following:
-
Reusable font assets. These may be large files, and since we're using a separate repo for storing them, We're not afraid of potentially having to do a git reset to purge stale assets. It won't impact the other repos with core app and library functionality.
-
Additional cross-cutting Rust libraries for dealing with fonts. It's uncertain whether it's better to have code packages as individual repos as one classically does, or whether we should take a more "biology-inspired" approach of copying innovations between repos as a form of lateral code/information exchange.
What's here
| Path | What |
|---|---|
fonts/ |
The font files, one directory per family, each with its licence. |
fonts/manifest.txt |
Machine-readable list of the fonts every app embeds: family, style, file, scripts, licence, SHA-256, pinned source. |
fonts/latin-manifest.txt |
Opt-in second manifest, same format: Latin presentation fonts (for SlideCraft and other document apps). Apps that read only manifest.txt don't get them. |
ATTRIBUTION.md |
Authors, pinned sources and licences. |
crates/craft-fonts |
Rust: the manifest as a static table, finding a checkout (CRAFT_FONTS_DIR), loading it, and an embed feature that compiles the fonts in. |
crates/craft-fonts-tests |
Tests asserted on these fonts (both manifests): checksums, licences, family names, Japanese coverage and outlines, vertical-text (vert/vrt2) support, Latin coverage and outlines, variable vs static styles. |
docs/integration.md |
How an app uses craft-fonts as a fully optional build input. |

How the apps use it
Fully optional, never required. The apps don't list craft-fonts in Cargo.toml (Cargo would
fetch it for every build). Building with CRAFT_FONTS_DIR=<path to this checkout> makes an app
embed the fonts in fonts/manifest.txt (and, for apps that opt in, fonts/latin-manifest.txt); without it, the app builds and runs as before. Release
builds check out a pinned commit of this repo and set the option. See
docs/integration.md.
Font assets for the Crafting Apps belong here, not in the app repos: add the file, its licence, a manifest line and an attribution row, and the tests check it.
Develop
cargo test --workspace # all font assertions
cargo test -p craft-fonts --features embed # the embedded bytes match the files
cargo test -p craft-fonts --features embed-latin # same, for the Latin manifest
