Prevent 1px seam between mobile bottom bar and bottom menu

[Copilot]

On some mobile render paths, the bottom offcanvas menu could leave a visible 1px gap above the fixed bottom bar. This change makes the layout intentionally overlap by 1px to avoid any seam.

• Mobile bottom-menu positioning

  • Updated the offcanvas bottom menu offset to overlap the fixed bottom bar by 1px.
  • Change applied in SCSS source and propagated to compiled CSS artifacts.
