github-devloop PR review decision: approve
三方裁决: minimal=approve structural=approve delete=approve

minimal:
The PR head matches the reviewed SHA, the diff is limited to the requested four static pages plus homepage navigation and shared CSS, it avoids package/script/workflow behavior changes, and the required check is green, so the minimal viable decision is to advance it.

structural:
The diff preserves boundaries: it adds static site pages and limited shared CSS/nav only, leaves package/script/CI behavior untouched, keeps EN/zh mirrors and existing link structure, and describes data-flow contracts such as source_ref payload pointers without altering engine or package contracts.

delete:
The PR head matches the reviewed SHA, and the diff is narrowly additive: four static bilingual pages plus homepage nav and shared CSS, with no package/script/CI behavior changes, no new framework or runtime indirection, and the added scope is justified as concise site content rather than brittle machinery.
