Pull request overview
This PR optimizes initial page loading in the standalone client by removing a redundant styles.css preload and adding modulepreload hints for the ES modules that are executed at the end of the document, helping start their fetch earlier and reducing a late-start network waterfall.
Changes:
- Removed redundant
<link rel="preload" ... as="style">forstyles.css(stylesheet is already immediately discovered via<link rel="stylesheet">). - Added
<link rel="modulepreload">forcloud-sync.jsandanalytics.jsto start module fetching during HTML parsing. - Kept existing
modulepreloadforapp.js, aligning resource hints with the module script tags at the bottom of<body>.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head39d564617eeec2ec65f7b5dbd22b0e48867c3ebd. -

💡 What:
index.html에서 불필요한styles.csspreload를 제거하고cloud-sync.js및analytics.js에 대한modulepreload링크를 추가했습니다.🎯 Why: 기존에는
<link rel="stylesheet">가 바로 뒤에 있음에도<link rel="preload" href="styles.css" as="style" />가 중복 사용되어 실질적인 이점 없이 브라우저 경고를 유발할 수 있었습니다. 또한,<body>하단에 위치한 ES 모듈들의 네트워크 요청이 늦게 시작되는(network waterfall) 현상을 방지하기 위해modulepreload리소스 힌트를 적용하여 모듈 탐색과 가져오기 시점을 앞당겼습니다.📊 Impact: 페이지 렌더링을 차단하지 않고 중요한 ES 모듈 스크립트를 조기에 가져오도록 브라우저에 지시함으로써, First Input Delay (FID)와 Time to Interactive (TTI) 수치가 개선될 것으로 기대됩니다. 중복되는 리소스 힌트의 제거로 브라우저 경고를 방지합니다.
