The custom nav cluster (theme toggle + Fund + GitHub Star) rendered inline at
every width, overriding VitePress's responsive collapse: a horizontal scrollbar
at 768-959px and off-screen clipping of the buttons on 1280-1366px laptops.
Show the custom cluster only at >=1440px where it fits, defer to VitePress's
native nav below that, anchor the flyout menu to the start edge in RTL, and drop
the redundant "Home" nav link so the nav fits at 768px.
Closes#556
The docs e2e suite clicked navbar and sidebar controls before Vue hydrated the
multi-locale bundle, so the clicks were swallowed. That raced the Pagefind
search open (filed as #551), the appearance toggle, and the homepage and
sidebar navigation tests. The old search tests also matched an input
placeholder the config overrides, so they failed against a working build.
Add a waitForHydration helper (gates on #app.__vue_app__, set inside Vue's
app.mount()) and an openDocsSearch helper, and route the affected tests through
them. Search itself was never broken; this change is test-only. Docs e2e suite
is green (43/43).
Closes#551
