📄 Description

Summary

EcosystemBar injected the bootstrap-icons stylesheet from jsDelivr with no integrity attribute. If jsDelivr was ever compromised or its CDN served modified bytes, the browser would apply the foreign CSS on every StaffML pageview.

Changes

  • Add integrity=\"sha384-…\" pinning the v1.11.3 bytes. Hash computed from the actual CDN file: 
    curl -sL https://cdn.jsdelivr.net/npm/bootstrap-icons@1.11.3/font/bootstrap-icons.min.css \
  | openssl dgst -sha384 -binary | openssl base64 -A
  • Add crossOrigin=\"anonymous\" — required for SRI to be enforced on cross-origin resources.
  • Add an onerror handler that logs to console (with the recompute recipe) when the stylesheet is rejected. Without it the only symptom of a stale hash (e.g. after a version bump) would be silently missing icons across the bar.
  • Comment includes the recompute recipe so future version bumps update the hash deterministically.

Test plan

  • npx tsc --noEmit → unchanged (the 2 pre-existing errors on dev about katex / js-quantities are local-env-only; those packages are declared in package.json but missing from local node_modules until npm install runs)
  • All 57 individual vitest cases still pass. The 4 test files that fail to import on dev fail with the same stash-in / stash-out behavior — unrelated to this PR.
  • Manual: load the site, confirm icons (envelope, github, etc.) still render. If the hash is wrong they'd vanish.
  • Manual: temporarily corrupt the hash, reload, confirm the new console.error fires with the recompute recipe.
