[Bug]: Custom Font import fails with "Could not download the selected Google Font" (save handler calls the Google Fonts lookup for custom fonts)

[webbasica]

Summary

Cause

In the save handler (dist/main-*.js), the Google Fonts lookup runs unconditionally, including for category === "custom-font", and its result replaces the file that was just imported:

const b = await Grt(g.family, c),   // fetch https://fonts.googleapis.com/css2?family=<family>:<variants>&display=swap
      w = { ...g, files: b },       // overwrites files{} from the custom upload
...
await d(w)

Any failure there is caught and reported as "Could not download the selected Google Font", which is misleading in the custom-font flow.

The downstream uploader is already custom-font aware — d() skips the remote fetch via if (g.category !== "custom-font") — and the REST endpoint AllPoints.php::handle_font_upload accepts woff, woff2, ttf, otf, eot and writes the decoded file correctly. It's simply never reached: during a failed attempt, no request to upload-fonts appears in the server access log, so the whole thing fails client-side before any save.

Two smaller points about that lookup:

• css2 rejects the family=<name>:400 variant syntax with HTTP 400 — including for Google families such as Roboto. Only :wght@400 returns 200.
• CORS is not involved: fonts.gstatic.com returns Access-Control-Allow-Origin: *, and the server can reach both fonts.googleapis.com and fonts.gstatic.com (verified 200).

Suggested fix: skip Grt() when category === "custom-font" and pass the imported files straight through to d(), as the uploader already expects. A more accurate error message for genuine Google failures would help too.

Workaround: upload the .woff2 manually into uploads/core-framework/fonts/ and declare the @font-face by hand.

Web app

Steps to reproduce

1. Fonts → Import Custom Font.
2. Upload a font file whose family is not on Google Fonts (mine is Century Gothic, a licensed Monotype face). The preview loads correctly in the panel.
3. Click Save.

Expected behavior

The uploaded file is saved to uploads/core-framework/fonts/ and an @font-face is generated for it.

Actual behavior

An error toast, "Could not download the selected Google Font", and nothing is saved. It happens with both WOFF and WOFF2.
