VersaTiles SDF font glyphs for MapLibre GL JS. 10 font families (Fira Sans, Lato, Libre Baskerville, Merriweather Sans, Noto Sans, Nunito, Open Sans, PT Sans, Roboto, Source Sans 3) bundled locally from versatiles-org/versatiles-fonts GitHub releases. Installed so the notebook's shortbread MapLibre cell renders labels without hitting tiles.versatiles.org as a runtime font CDN. Re-exported by the versatiles-frontend layer's http.server at /fonts/. MUST be invoked before building, deploying, or troubleshooting the versatiles-fonts layer.

versatiles-fonts — SDF glyph PBFs for MapLibre
Layer properties
| Property | Value |
|----------|-------|
| Dependencies | supervisord (transitive; no service of its own) |
| Distros | arch + fedora |
| Build deps | curl, jq |
| Install path | /opt/versatiles-fonts/ |
| Re-exported at | /opt/versatiles-frontend/fonts/ (by the versatiles-frontend layer) |
What it ships
versatiles-org/versatiles-fonts releases a fonts.tar.gz containing
all 10 font families pre-rendered as SDF (signed distance field) PBFs
that MapLibre GL JS can fetch via its standard glyph URL template:
{glyphs}/{fontstack}/{range}.pbf
The directory layout inside the tarball (verified at install time):
versatiles-fonts/
├── Fira Sans Regular/
│ ├── 0-255.pbf
│ ├── 256-511.pbf
│ └── ...
├── Noto Sans Regular/
│ ├── 0-255.pbf
│ └── ...
├── Roboto Regular/
│ └── ...
└── ...
MapLibre glyphs URL pattern
The notebook's shortbread cell patches the style's glyphs URL:
style.glyphs = 'http://127.0.0.1:28002/fonts/{fontstack}/{range}.pbf';
MapLibre substitutes {fontstack} (e.g. Noto Sans Regular) and
{range} (e.g. 0-255) when fetching each glyph range as the user
pans/zooms. The versatiles-frontend http.server serves the files
directly — no special URL rewriting needed.

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).
