## Summary - Adds a `MobileBackButton` component (mobile only) on Budget and Account detail pages - At rest: replaces the logo icon in the header with a styled back button - On scroll (>40px): a floating pill button appears top-right with the same glass/backdrop-blur style as the bottom nav bar, with a smooth 300ms slide+fade animation - Extends `AppSidebarLayout` and `AppSidebarHeader` with an optional `mobileLeading` slot that falls back to `AppLogo` when not provided |
