Conversation
Opening a navbar dropdown (e.g. Community) locks body scroll via `overflow: hidden`, removing the viewport scrollbar and shifting the whole page sideways by the scrollbar width on scrollable pages. Reserve the scrollbar gutter with `scrollbar-gutter: stable` on `html` so the layout width stays constant whether or not the scrollbar is present.

Problem
Opening a navbar dropdown (e.g. Community) locks page scroll by setting
body { overflow: hidden }(src/components/navbar/navbar.tsx). On pages tall enough to show a scrollbar, this removes the ~15px viewport scrollbar. Because no space was reserved for it, the whole page — including the full-width navbar — shifts sideways by the scrollbar width as the menu opens and back when it closes.Fix
Reserve the scrollbar gutter on
htmlso the layout width stays constant whether or not the scrollbar is present:This is consistent with the
scrollbar-gutter: stablealready used on.nextra-scrollbar, and also covers the mobile menu and any other scroll-lock.Verification
Measured the navbar's right edge while clicking the Community trigger:
autostableThe scroll-lock still works as before; it just no longer shifts the page.
