Inter is now served from this site, and the page no longer references Google. `bun test` passes (7 tests). I did not load the page in a browser, so the "same look" and "no off-origin requests" checks are still open.

Inter is now served from this site, and the page no longer references Google. bun test passes (7 tests). I did not load the page in a browser, so the "same look" and "no off-origin requests" checks are still open.

Font file: public/fonts/inter-5.3.0-latin.woff2 is the variable woff2, latin subset, 48 KB. I could not reach Google from the sandbox. I took the file from the @fontsource-variable/inter 5.3.0 npm package, which is the same upstream Inter. The OFL licence is next to it in public/fonts/inter-LICENSE.txt.
Page: public/index.html drops the two Google preconnects and the stylesheet link. It adds a preload for the woff2.
CSS: public/style.css gets an @font-face for Inter at weights 100–900 with font-display: swap and the latin unicode-range. The font-family stack is unchanged. It is now a variable font, so 400, 500 and 700 render from the same file.
Server: in src/server.ts the CSP is now style-src 'self'; font-src 'self'. I added a woff2 MIME type. Fonts are cached for a year as immutable, which is safe because the file name carries the Inter version.
Tests: test/server.test.ts now asserts the CSP and the HTML contain no google or gstatic, and that font-src 'self' is set. A new test checks the font is served as font/woff2 with an immutable cache header.
README: a short Fonts section covers where the font comes from and why the file name is versioned.

I did not run bun x tsc --noEmit: the repo has no tsconfig.json or package.json, so it only printed tsc's help text. There is no scripts/gate.ts, scripts/fast.ts or docs/VISION.md in this repo, so I skipped those steps. I did not touch public/site.js or public/sky.js.

To try it, open the preview with the network panel filtered by domain. You should see only the preview origin (plus the forge's /live call), and the Inter woff2 should load from /fonts/.

Verified on the preview: the HTML has no Google references or preconnects, and the font is preloaded from /fonts/. The woff2 is served as font/woff2 with cache-control public, max-age=31536000, immutable. The CSP is now style-src and font-src 'self' with no Google hosts. No inline <style> or style= attributes exist, so the tighter style-src breaks nothing; site.js sets styles through CSSOM, which CSP allows. The @font-face is variable 100-900 with swap, the font-family stack is unchanged, the OFL licence ships beside the file, and the tests cover the CSP, the HTML and the font response. I could not render the page in a browser, so the visual match is unchecked.

Two things I would do next:

Add size-adjust, ascent-override and descent-override on a local fallback face, so the swap from the system font to Inter causes no layout shift on first paint. A preload already narrows the gap.
Add a test that every /fonts/ URL referenced in style.css and index.html resolves to 200, so a version bump that renames the file cannot leave a broken preload.
