The feed's show/content chips, source, count, sort and view switcher —
plus the active-filter chips — lived inside the scroller, so they
scrolled away with the cards; only the SearchBar strip stayed fixed.
Give PageShell a fixed toolbar band (filled by a module via the new
PageToolbar portal) above the scroller. On the feed page the toolbar +
chips portal into it and stay put — and removable — while cards scroll.
The channel-embedded Feed (channelScoped) keeps its inline toolbar,
which rides with the banner/tabs as before.
Verified both entry points at desktop + 1000px (toolbar wraps in-flow,
band grows, still pinned); E2E 11/11; tsc + knip clean.
