/* Mobile: the small floating panel doesn't work well on a phone screen
   (cramped, and the on-screen keyboard can cover the input) — go
   near-full-screen instead, like most mobile chat widgets.

   `top`/`height` here are a CSS-only fallback (16px margin, matching
   the JS-driven sizing below) for browsers without window.visualViewport.
   Everywhere that matters, js/index.html's syncPanelToVisualViewport()
   overrides these as inline styles, pinned to the actual visible
   viewport — plain `dvh` alone isn't reliable enough against real
   on-screen keyboards (confirmed on real Android/Chrome: the header
   ended up scrolled out of view under the keyboard). */
