+Significance: patch
+Type: changed
+
+My Jetpack: adopt the shared `jetpack-admin-page-layout` mixin on the main dashboard page so its layout (sticky header, internally scrollable middle, JetpackFooter pinned at viewport bottom) matches the rest of the Jetpack admin pages. Drop the bespoke Hello Dolly position-absolute override — Dolly now uses the same centralized normalize as every other Jetpack admin page. The full-width tab separator no longer uses `width: 100vw` (which overflowed the new viewport-fitted column by the wp-admin sidebar width); it now spans the page column instead. Interstitial / full-screen mode (`.jetpack-admin-full-screen`) is intentionally excluded from the mixin so it keeps its current take-over-the-viewport behavior.
