  /* Phones: the form is taller than the screen (label-above-input + 44px touch
     targets), so it MUST scroll. Two WebKit-specific traps to avoid — and iOS
     Safari AND iOS Chrome are both WebKit, so this hits every iPhone:

     1. A flex scroll-container that centres an overflowing child (align-items /
        justify-content: center) clips the child's TOP outside the scroll range —
        the card's logo jams against the top edge and can't be scrolled to.
     2. A position:fixed overlay extends behind the browser's bottom toolbar, so
        the last element (the Send button) parks behind the bar, untappable.

     Fix: drop flex on phones. Plain block flow scrolls the overlay from the top,
     keeping the whole card reachable (top never clipped). Bottom padding — plus
     the safe-area inset — lifts the Send button clear of the toolbar. The card
     grows to its natural height; the overlay is the single scroll container. */
