🎯 Issue Triage

The website's Starlight table of contents (ToC) sidebar overflows and clips behind the page footer when the ToC is long, visible on the release notes pages.

Category: Bug
Area: meta:website

⚠️ No TypeSpec reproduction code (this is a website layout/CSS issue). Reproduction page: (typespec.io/redacted)

🔍 Analysis

• Affects the Starlight-based documentation site (website/ package)
• The ToC sidebar is likely using position: sticky or overflow: visible without a max-height constraint relative to the viewport, causing it to extend past the footer
• Fix likely involves constraining the ToC container height (e.g., max-height: calc(100vh - <footer-height>)) or adjusting the sticky positioning offset
• No duplicates found

📝 Suggested next steps

• Inspect the Starlight ToC CSS in website/ for sticky/overflow settings
• Apply a max-height or viewport-relative constraint to prevent overflow under the footer
