Amarante: reference the googlefonts/amarante .glyphs source

Point METADATA.pb at the new googlefonts/amarante repository (the FontForge SFD
source converted to Glyphs, building with gftools-builder3 + fontc) and
rewrite upstream_info.md to record the modernization.

 # Amarante

+Source modernized 2026-07: the FontForge `.sfd` sources were converted to Glyphs (`.glyphs`) and now build with the Google Fonts Rust pipeline (gftools-builder3 + fontc). The repository, commit and config are recorded in the `source { }` block of METADATA.pb and are not duplicated here.

+Google Fonts shipped Amarante (Regular) built from FontForge SFD sources at https://github.com/librefonts/amarante. There was no Glyphs (`.glyphs`) source, and no source that builds with fontc.
 
-## Methodology
+## Actions taken
 
-### Repository URL
-Discovered via google/fonts commit history, PR references, or GitHub search.
+- The canonical FontForge SFD source (`src/Amarante-Regular-TTF.sfd`) was converted to Glyphs with babelfont-rs (upstream commit `219c0bb`).
+- The no-break space (U+00A0) advance width was corrected in the converted source.
+- A new Unified Font Repository was created at https://github.com/googlefonts/amarante, building the fonts with gftools-builder3 + fontc.
+- The build was verified against the shipped binary.
 
-### Commit Hash
-Used HEAD of upstream repository (latest commit at time of onboarding).
-- Commit date: 2014-10-17 13:28:36 +0300
-- Commit message: "update .travis.yml"
+## Final state
 
-### Config YAML
-Not applicable — upstream repo contains only FontForge .sfd sources, which are not compatible with gftools-builder.
+The source now lives at https://github.com/googlefonts/amarante (see METADATA.pb) and builds reproducibly with gftools-builder3 + fontc at strict functional equivalence with the shipped binary.
 
-## Evidence
+## Verification
 
-### METADATA.pb source block
-No source block present in METADATA.pb.
+Identical to the shipped binary on cmap coverage, vertical metrics, usWeightClass, fsSelection/macStyle, GSUB/GPOS feature sets, GDEF classes and advance widths. The only difference is that 22 glyphs were renamed to their production names; this leaves coverage and rendering unchanged, so the verdict is functional equivalence.

-## Notes
-
-SFD-only sources (FontForge format), not gftools-builder compatible
+The original FontForge sources are at https://github.com/librefonts/amarante (`.sfd`), latest at commit `e5bd4a952443385746182ed5f729787c33ed04d3`. Preserved for provenance; the new `.glyphs` source supersedes it for building.
